## What
**Layers panel from the keyboard** (two of the three open items of area 3, plus long-list QA)
- **F2 renames** the selected layer (a second key for `object.rename`, next to Cmd/Ctrl+R) from the canvas, after a click on a row, or from a layer row that has the keyboard (F6 mode, where the canvas shortcuts are off, so the layers branch of `a11y::keys` runs it). When the rename ends the row gets the keyboard back (`a11y::refocus_row`); Escape in the field cancels and stays in the panel instead of jumping to the canvas.
- **Shift+F10 opens the context menu** (`view.contextMenu`, a new command that only asks the UI): at the focused layer row when the layers panel has the keyboard (F6 or a clicked row), else on the canvas just below the selection (the middle of the canvas with nothing selected). The menu takes the keyboard like the other menus opened from the keyboard (`a11y::popup`), and Escape gives it back to the row or the canvas. The Menu key can't be supported: egui 0.36 has no key for it.
- **Keyboard box selection** (`select.area`, F8): for keyboard-only users, a selection box appears around the selection (or in the middle of the view); the arrows move it, Shift+arrows move its far corner (10 screen pixels a press), Enter selects what it covers exactly like a marquee (Shift+Enter toggles, Cmd/Ctrl+Enter takes nested layers), Escape or a click drops it. A toast and the canvas's screen-reader description say the box's size and the keys. With a box (`{x, y, width, height, add?, deep?}`) the command selects directly, for agents. The marquee's rules (top-level layers, frames only when covered, the children of the frame the box starts in, the focus view, Shift toggling) moved into `Session::marquee_within` / `marquee_selection`, shared by the pointer marquee and the command.
- **Long lists (10k layers)**: a test that a layer near the bottom of a 10k-layer list is revealed (parents expanded, list scrolled) and that F6 lands the keyboard on its row and the arrows walk on from it; the UI bench (`perf_ui_frames`) gained rows for expanding every layer, arrow keys down the expanded list, revealing a layer at the bottom and collapsing everything. Release, 10k layers: first frame with every layer expanded 1.22 ms, an arrow key 1.04 ms, reveal 0.30 ms, collapse all 0.37 ms, idle 0.17 ms.
**Stroke styles** (area 6)
- What the public documentation describes for strokes was mostly already in: colour styles apply to strokes from the stroke section's style picker (`style.apply {target: "stroke"}`, linked, following `style.update`, one undo step, `style.detach {which: "stroke"}` keeping the colour), and the stroke weight binds to number variables. A test now covers that path.
- Missing piece, added: **each side's stroke weight binds to a number variable on its own** (`strokeTopWeight`, `strokeRightWeight`, `strokeBottomWeight`, `strokeLeftWeight`): `node.set` keys (setting or binding one side turns on individual strokes with the other sides at the weight), the stroke-weight variable scope, the stroke override group for instances, and REST `boundVariables` import. The Design panel's per-side fields are bindable, two to a row like the corner radii so a variable's name fits.
New strings go through `tr(...)` with `en.toml` / `es.toml` entries, and the two new commands have Spanish labels. Shortcuts are only in `keymap.rs`. Nothing redraws while idle (the box draws only when a key moves it). Selecting from the box leaves no undo step; each stroke edit is one.
## Verified
- **Desktop app** over the control channel (`target/debug/figcraft.exe` from this worktree's target dir, `--control <free port>`, separate `APPDATA`, keys sent as real `ui.input` key events, stopped by PID): F2 on a selected layer opens its name field in the layers panel (screenshot), typing and Enter rename it; F6 to the layers panel, Shift+F10 opens the menu at the Avatar row with Copy focused (screenshot), Escape gives the keyboard back to the row, F2 + typing + Enter renames it and the row keeps the keyboard ("Profile"); Shift+F10 on the canvas opens the menu for the selected frame with Copy focused (screenshot); F8 shows a box around the selected frame, Shift+arrows stretch it over a second layer (screenshot with the hint toast), Enter selects both; a rectangle with the colour style "Brand/Accent" on its stroke and its top weight bound to a number variable (screenshot: the style chip in the stroke section, the red stroke thicker at the top, the per-side field showing the variable).
- **MCP**: `figcraft-cli mcp` (headless): created a paint style, `style.apply {target: "stroke"}`, `object.rename`, bound `strokeLeftWeight` to a variable and ran `select.area` over the layer; `inspect_document` shows the name "Outlined card", `styles.stroke: "S:1"` with the style's colour on the strokes, `strokeSides [2, 2, 2, 6]`, `boundVariables {strokeLeftWeight}`, and one undo step per command.
- **Web**: `cargo xtask wasm` passes (part of the gate).
- **Performance**: release UI bench at 10k layers (numbers above).
- `cargo +1.99.0 xtask ci` passes (fmt, clippy, tests, layers, assets, wasm), after merging #131 and #132.
## Tests
- `ui-egui` `layers_keyboard_tests` (3): F2 from the canvas and from a focused row (the row gets the keyboard back, Escape cancels without leaving the panel); Shift+F10 at a focused row, on the canvas below the selection and after a clicked row, the menu taking and giving back the keyboard; F8: the box around the selection, the screen-reader description, Shift+arrows sizing, Enter selecting, arrows moving it without nudging layers, Escape, the middle of the view with nothing selected, a click dropping it.
- `ui-egui` `perf_tests::a_layer_revealed_at_the_bottom_of_10k_layers_gets_the_keyboard_on_its_row`, plus the new bench rows.
- `engine` `select_area_tests` (2): marquee rules through the command (negative sizes, frames, starting inside a frame, deep, add toggling, empty spots), the UI request with no box, bad boxes refused (the junk sweep covers both new commands too).
- `engine` `stroke_style_tests` (2): a colour style on strokes (link, undo, style edits, detach); stroke weight and per-side weights bound to variables following the frame's mode, `node.set` per-side keys, scopes and override groups.
## Not in this PR
- The Menu (application) key: egui 0.36 doesn't deliver it.
- Enter doesn't rename: on the canvas and a focused row it already selects children / activates the row.
- The keyboard box doesn't pan the view when it is moved off screen (zoom and pan keys still work while it shows).
- Shift+F10 does nothing while a toolbar or properties control has the keyboard.
- Progress docs: area 3 95%/78% → 98%/82%, 2–4 h → 1–2 h; area 6 90%/72% → 95%/75%, 1–3 h → 1–2 h; mainstream depth 67.8% → 68.1%; percentages unchanged at this rounding; full parity ~323–621 h → ~322–618 h (target-app-parity, ROADMAP); ui-parity rows (context menus, keyboard box selection, layers from the keyboard); `docs/mcp.md` documents `object.rename` without a name, `view.contextMenu`, `select.area` and stroke styles and variables.
## What
**A text behaviour suite written from the public documentation, and fixes for every divergence it found.** Each documented rule (Auto / % / px line height and how the leading is split, letter spacing in % and px, paragraph spacing and indent, auto width / auto height / fixed / truncate with max lines, vertical trim, decorations from the font's metrics) is a table-driven case with the numbers the rule implies and a one-line derivation, read from the face actually used so it holds on any machine with a font. CJK line breaking follows UAX #14 and the CJK line-start / line-end rules; caret steps follow UAX #29 grapheme clusters. Where the documentation is silent the case says so and pins today's behaviour.
**Fixes (6 of the 13 text cases fail on the old layout; the break and caret rules are new functions)**
- **CJK line breaking**: lines break between ideographs, kana and Hangul and before or after a Latin word next to them (before: no break before an ideograph that follows Latin, none after `。`, full-width forms, CJK punctuation or Extension B ideographs), never inside a Latin word, with kinsoku: closing brackets and quotes, `、。，．！？`, small kana, the prolonged sound mark and iteration marks never start a line (the character before moves down with them), opening brackets never end one. The ideographic space hangs at the line's end like a space. One small break-class table in `crates/text/src/breaks.rs`, no new crate.
- **Fallback fonts no longer move the baseline**: a style's ascent, descent, line height and cap height come from its own font, not the fallback face that drew some of its characters, so a line with CJK or emoji keeps the height and baseline of a Latin line (with a fixed line height the mixed line's baseline used to shift by the CJK face's taller metrics; with Auto the line grew). Decorations likewise use the style's font and size, so an underline runs at one height and weight through mixed scripts (and isn't thinned by synthesised small caps).
- **Paragraph indent applies to left-aligned text only** (documented); right-to-left paragraphs keep it when right-aligned (their start). The Type settings field is disabled with a hint otherwise.
- **Carets by grapheme cluster**: Left / Right, Delete and Backspace step over a whole emoji ZWJ sequence, flag, skin-tone sequence or letter with combining marks (they moved one code point at a time, leaving the caret inside an emoji and deleting half of it). A cluster is also shaped with one font, so a joiner or variation selector no longer splits an emoji sequence across faces.
- **Words by script**: double-click and word moves (Alt on macOS, Ctrl on Windows and Linux) take one script's run in text without spaces (`日本語` | `の` | `テキスト`), Hangul words end at spaces, and a Latin word keeps its combining marks (before: a whole CJK sentence was one word, and `cafe` + combining acute split at the accent).
**Missing documented setting, added**
- **Vertical trim** (cap height to baseline): `leadingTrim: none | capHeight` (`CAP_HEIGHT` from REST JSON) through `node.set`, a Standard / cap-height segmented control in Type settings, `inspect_document` and Dev Mode properties, CSS `text-box: trim-both cap alphabetic` in generated code. The box runs from the first line's cap height to the last baseline (auto height shrinks, auto layout parents follow); truncation counts the trimmed bottom; exports reach past the box so descenders below the last baseline aren't clipped. Canvas, PNG, SVG and PDF all draw from the same layout.
New strings go through `tr(...)` with `en.toml` / `es.toml` entries; the new segmented control reuses the Type settings one (accessible toggle names). Each edit is one undo step. `unicode-segmentation` (already in `Cargo.lock` through egui and winit) became a direct dependency of `figcraft-text`.
## Verified
- **Desktop app** over the control channel (own target dir, separate `APPDATA`, stopped by PID): a 200 px auto-height box of Japanese wraps with no line starting with `、。」` and `「` never ending a line (`…テスト` / `を折り返す、テスト` / `です。「括弧」は行` / `末に来ません。漢` / `字とかなとカタカ` / `ナ。`, the last `ナ` carried down with `。`); a Latin / CJK / Latin paragraph at 36 px line height is 108 px with evenly spaced baselines; the same text with vertical trim is 89.45 px (cap height 17.45 + 2 × 36), its box running from the cap height to the last baseline, and the Type settings control turns it off (108 px) and undo brings it back in one step; one Right arrow from after `a` in `a👨👩👧b` lands after the whole family emoji and Shift+Right then selects `b`; a double click selects the katakana run テキスト.
- **MCP**: `figcraft-cli mcp` (headless) built the same three texts; `inspect_document` reports 108 px for the 36 px paragraph and 89.42 px with `leadingTrim: capHeight` for the trimmed one (cap height of the headless font), the PNG export wraps the Japanese by the same rules and keeps the trimmed text's descenders, and `inspect.code` emits `text-box: trim-both cap alphabetic`.
- **Web**: `cargo xtask wasm` passes (part of the gate).
- **Performance**: text layout of a 2,250-char Latin and a 2,000-char Japanese paragraph wrapped at 300 px (release, median of 7 × 30 runs) before and after on the same machine: Latin 0.70 → 0.42–0.50 ms, Japanese 0.46 → 0.37–0.47 ms (within noise or faster: line metrics are now computed once per style change instead of per glyph). All-ASCII text skips grapheme segmentation.
- `cargo +1.99.0 xtask ci` passes (fmt, clippy, tests, layers, assets, wasm), after merging #131 and #132.
## Tests
- `text` (`behaviour_tests`, 13 tests): line height Auto / % / px; leading split above and below every line (positive and negative); letter spacing % / px / negative; paragraph spacing and indent by alignment; resizing and truncation with max lines; vertical trim (heights, first baseline, glyph spacing kept, truncation); decorations from the font's metrics through mixed scripts; fallback fonts keep line height and baseline (Auto, px, %); 22 break-opportunity cases; CJK wrapping with kinsoku, Latin words in CJK and Korean; the ideographic space hanging; grapheme steps over ZWJ families, flags, combining marks, skin tones and emoji presentation; one face per cluster. Font-dependent cases skip on a machine without fonts.
- `engine` (`text_behaviour_tests`, 5): arrows, Shift+arrows, Delete and Backspace by cluster; double-click and word moves by script (and through `keymap::text_motion` for Ctrl and Alt); IME composition with CJK wrapping and growing the box before commit; vertical trim through `node.set` (box size, PNG ink at the top, export bounds below the box, SVG and PDF, CSS, inspect, undo, junk refused, REST spelling); paragraph indent only on left-aligned text.
- `format` REST import test covers `leadingTrim: CAP_HEIGHT`.
## Not in this PR
- Documented but not modelled yet: list spacing, hanging quotes and hanging lists, underline style / thickness / offset / skip ink.
- Documentation silent, behaviour pinned: Korean wraps by syllable (no word mode); Han compounds next to each other are one word (no dictionary segmentation); letter spacing is added after the last character too; a fallback font's taller glyphs may overflow the line rather than grow it.
- `.fig` import doesn't read vertical trim yet (the field wasn't checked against real files).
- Spell check (on hold, #113).
- Progress docs: target-app-parity area 10 85%/64% → 87%/68%, 7–13 h → 5–10 h with the suite listed under text editing depth; feature breadth and ready for real work unchanged at this rounding; full parity ~323–621 h → ~321–618 h (target-app-parity, ROADMAP); ui-parity text row.
A selection and transform behaviour suite derived from public documentation, with fixes: Alt-resizing shrinks as well as grows; groups, Scale-constrained frames and multiple selections resize each layer along its own axes keeping rotation and flip; several layers flip together past an edge; a flipped layer reads back the typed rotation; resizes land on whole pixels with the pixel grid; presses inside tiny layers move them; locked layers get no handles; a marquee can start on a top-level frame's background; select inverse skips hidden layers. Adds equal-spacing snapping with labelled gaps and Cmd/Ctrl to ignore constraints while resizing a frame.
.fig files open through file.open, file.import, drag and drop, the dialogs, the CLI and MCP. A generic reader written from the public format description decodes the zip, the deflate/zstd chunks and the kiwi schema and message, then maps nodes by field name onto the REST importer: layer tree, geometry, paints with styles resolved, strokes, effects, text runs, vectors as outlines, auto layout including grid, constraints, components, sets, instances expanded from their main with overrides, styles, variables with modes and bindings, prototyping and image fills. Unsupported layers come back as warnings. Fuzzed; tested on fixtures generated in code. New dependency: ruzstd (pure-Rust zstd decoder).
Found and fixed in a Windows pass of everyday workflows: unsaved documents are now copied in the background (at most every 10 s) and offered back after a crash or forced quit (file.recover); Ctrl+arrow / Ctrl+Backspace / Ctrl+Delete text motion follows Windows and Linux conventions (keymap::text_motion); number-field scrubbing keeps its value; typing in a Tab-focused field works; default linear gradients and their handles behave; Escape closes dialogs without deselecting; clipped panel hints wrap; the unsaved-changes dialog is translated.
A 64-case behaviour suite derived from public documentation (sizing, padding, strokes, gaps, alignment, wrap, absolute position, grid, stacking) plus command-level tests. Fixes: frames never shrink below their padding, only the frame's own inside stroke counts when strokes are included (now the default for new auto layout), auto gaps stop at 0, grid fr tracks never go below their content, and canvas stacking (reverseZ) now drives drawing, exports and hit testing. New settings: evenly/around auto gaps, vertical wrap with a column gap, per-child grid cell alignment, strokes included/excluded and canvas stacking in the Design panel.
True wide-gamut display is blocked upstream (egui-wgpu 0.36 always picks an 8-bit sRGB surface and draws sRGB-encoded UI), so the colour picker warns when a Display P3 colour is outside sRGB and View > Soft-proof sRGB stripes the canvas pixels sRGB can't show. Exports keep wide-gamut colours as before.
File > New window, Open in new window on a tab, and dragging a tab out open files in separate OS windows (egui deferred viewports, redrawn only when needed), sharing one session, preferences, libraries and clipboard. Closing a window asks about unsaved files (the main window now asks too); closing the last window quits. window.new / window.list / window.focus and per-window screenshots for the control channel and attached MCP. The browser keeps one window.
UI strings come from per-language TOML catalogs compiled in (English text as the key and fallback, named placeholders, one/other plurals, context suffixes); command labels are translated at display time while ids, CLI, MCP and control output stay English; accessibility names follow. Preferences > Language (System / English / Español, live; the system language from the OS or the browser), pref.language for scripts. A key check test guards the catalogs. The Spanish catalog is a machine draft awaiting native review; docs/translating.md explains adding a language.
Clicks on a boolean group test its computed result, so a click in a subtracted hole reaches what is behind it. Layers inside a group, boolean group or instance stay in their parent when dragged (one shared rule). View > Frame outlines and Slices now draw. The idle test's flake came from the render worker clearing its in-flight flag before waking the UI; jobs now carry sequence numbers.
Components (or sets) can be linked per language to a real code component (import path, name, and a template whose {prop} and {prop ? "a" : "b"} placeholders take the instance's property values, escaped per language). Dev Mode's Inspect panel shows the connected snippet with its import for instances, a Connect to code editor with live preview, and read-only plugins. Links export to and import from figcraft.connect.json.
Strokes can use a brush: eight presets drawn in code (four stretched along the path, four scattered with spacing, size, rotation and offset jitter from a fixed seed), drawn by the shared stroke-outline code in canvas, PNG, SVG, PDF and outline stroke, with caps on copies and steps. Pointer events carry pen pressure; the Pencil records it as the stroke's width profile, which brushes follow (Windows pens and browser styluses; constant width elsewhere).
Text layers can follow a path (start offset, flip, alignment; edited in place; canvas, PNG, SVG, PDF; SVG textPath imports as real text on a path). A new pattern paint tiles a source layer in grid or hex rows with scale, spacing and alignment, live as the source changes (SVG pattern, PDF vector tiling pattern).
A file's library can be published to figcraft-server and enabled in other files by a share link (view access is enough); placing, styles, variables and library updates with overrides kept work as for local libraries, with a background check while the Assets panel is open. library.swap re-points instances, styles and variables to another library by name (one undo step, unmatched items listed). The server keeps per-file usage reports (library.usage).
Branches live inside the .figcraft file (base and head snapshots, own id space). Update from main and merge are three-way merges over the collaboration change sets; a conflict (same property changed on both sides, or delete vs edit) must be resolved branch-or-main before merging, which is one undo step on main. The review dialog reuses Dev Mode's compare view; branch tabs show a banner; File > Create branch; branch.* commands for CLI and MCP.
Animated GIF image fills keep their frames (first frame on the canvas and in exports; the presenter and preview play them, capped frames and memory, idle when not playing). TIFF images open, import, place and drop (pure-Rust decoder already in the tree); SVG exports embed TIFF and BMP as PNG. HEIC and video stay out (non-Rust decoders).
The last three catalogued menu items got commands: File > Open recent (recent files kept in preferences, capped, missing files greyed and dropped when picked, Clear recent), outlines for the selected layers only, and mask outlines. Menu breadth 100%.
Library collections can be extended in a consuming file (inherited modes, per-mode overrides with reset, extra variables; library updates keep overrides). Variables export to the REST JSON shape or CSS custom properties and import back (merged by name, validated by the REST reader, one undo step). Gradient stops and variant properties bind to variables. Also fixes clicking a gradient stop adding a new stop.
figcraft-server hosts many files over the same hub the app uses for sessions, persists each as a checksummed snapshot plus an append-only log (synced before replies, compacted, damaged files skipped and reported) so restarts lose nothing confirmed, and gives per-file share links with edit or view access (hashed 128-bit tokens, revocable). The app can publish a file to a server and join server-hosted files; view-only tabs refuse edits. Protocol version 2.
Boolean operands are editable in place with live results (per-operand operations, cached prefixes so a drag recomputes from the edited operand up); a Design panel Arc section; the shape builder takes strokes and open paths as outlined areas; variable width points can be wider on one side.
- Styles, variables, collections, modes and comment threads created in a live
session take ids from the creator's client space (figcraft_doc::ids: a
number from the node id allocator, client_id << 32 | counter); outside a
session ids are made exactly as before. The server refuses a new entry in
another connected client's space (removed entries can be put back by undo),
keeps removed entries in its saved state, and starts client ids above every
space used by any kind of id.
- Others' text carets and selected characters show on the canvas in their
colour at the glyph positions, with their name above the caret (no blinking,
no frames of their own). Typing in a layer someone else is typing in says so
(toast and tag); collab.peers reports who types where.
- Toasts wrap at a readable width.

- Browser client (step 4): the web build joins sessions a desktop app hosts
through the browser's WebSocket API (web-sys, binary frames, the same
message encoding). Its connection logic is a target-independent state
machine (collab-net driver.rs): hello on open, changes and presence held
until the welcome, throttled presence, keep-alive pings, a silent host
counted as dropped, reconnect with backoff, final refusals. Tested natively
against a scripted socket and a real host over loopback. Hosting stays
desktop-only (LiveLink::can_host; collab.peers canHost). https pages are
told up front that they can only reach ws:// sessions on this computer.
- Shared join logic (join.rs: GuestConfig, outcomes, taking in host messages)
and transport limits (limits.rs) used by the native guest and the browser.
- Invite links: `figcraft figcraft://join?...` joins on start (a bad link
opens the Join dialog with it); file:// arguments are paths. Windows
registers a per-user figcraft:// opener (HKCU\Software\Classes\figcraft)
behind a Registry trait (tests use a fake): collab.registerLinks {on?} and a
Preferences checkbox, default on for installed builds, never for builds
from source. macOS Info.plist declares CFBundleURLTypes; the Linux desktop
entry declares x-scheme-handler/figcraft and passes %U.
- Join dialog: Escape closes it and no longer reaches the canvas (selection
kept); its field has the keyboard when it opens.
- Docs: collab-protocol (browser client, links, mixed content), mcp,
control-protocol, README, web hosting notes, collaboration wording in the
progress docs (numbers unchanged).

* M9: fmt after merge
* M9: live sessions: host from the app, invite links, live cursors and presence
Step 2 of docs/collab-protocol.md, networking and presence half:
- crates/collab-net (layer 6): WebSocket transport (sync tungstenite, a
reader and a writer thread per connection, no async runtime), the
session host the app embeds (runs figcraft_collab::Server as the
authority, carries its messages), invite links, presence throttling
(~30 Hz, latest wins), limits (sockets, hello/idle timeouts, message
size, rate, slow clients), keep-alive, clean close, reconnect with
backoff; a browser stand-in until the web-sys client (step 4).
- engine: live session state (status, peers, presence, follow) and the
collab.host/stop/join/leave/peers/follow/cursor commands; the network
is reached only through the LiveLink the app installs.
- ui-egui: remote cursors (pointer drawn in code, name tag, gliding),
selection outlines (once documents sync), avatars in the right panel
with follow, the Share popover (start, invite link + URL with Copy,
stop), File > Join live session.
- desktop app and MCP headless session install the link; xtask layers
keeps networking crates out of L0-L5.
- Documents don't sync between apps yet (follow-up).
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* M9: live sessions: document sync between apps
- The host's session runs figcraft_collab::Server seeded with the shared
document; every app (the host's too, through the hub without a socket)
is a collab Client. Guests open the host's file from the welcome as a
new tab; leaving keeps it as a local copy.
- Engine: after each local action (a gesture once it ends; nothing during
version or text previews) the session document is diffed into one
Changes batch; server batches go through Client::receive with
EngineRecompute and are installed with Session::apply_remote, which
never touches the undo history. Batches arriving mid-gesture wait.
- Transport: Changes/Reject/Welcome reach the engine as Event::Sync;
LiveLink::send carries batches in order; hellos are limited to 64 KiB,
joined clients to the core's message size.
- Tests: engine sync against a real Server (ids in the client's space,
one batch per gesture, remote edits skip undo, deferral, closing the
file leaves), three apps over loopback converging (create, move,
recolour, delete, rename) and a late joiner getting the server's state.
- Docs: collab-protocol, mcp, README, roadmap docs; the UI's
"cursors only" note is gone, replaced by the per-person undo caveat.

command.batch now uses too) and is rolled back when it fails. Files,
other documents, the undo history, dialogs and plugins are off limits;
read-only plugins can't change the document. Installed plugins live in
the preferences; development plugins re-read their module every run.
- UI: installed plugins in the Plugins menu, a parameters form drawn
from the manifest, Manage plugins, Plugins > Development > Import
plugin from manifest.
- plugins/: a no_std Rust SDK and two example plugins (Tidy names,
Swatch grid), built for wasm32 by `cargo xtask plugins` (part of
`cargo xtask wasm`).
- Docs: docs/plugins.md (manifest, permissions, limits, ABI, SDK),
docs/mcp.md, docs/control-protocol.md, README, ROADMAP, parity.

- Compare changes: a ready-for-dev frame or section keeps a snapshot of itself from just before
its first change (Document::dev_snapshots, saved only while changed; dropped on resolve, re-mark,
other status or delete). `dev.compare {id?, show?}` diffs it layer by layer: added/removed
layers, and property changes formatted like Inspect (`width 120 → 136`, `fill #FF0000 →
#E03030`, text, parent, order, component, auto layout, typography, effects). The compare view
shows before / now side by side or overlaid with a slider, changed layers outlined, the list of
changes and Resolve change.
- Focus view: `dev.focus {id? | direction}` / `dev.unfocus`: one frame drawn and hit alone
(render Options::solo), a bar with name, status, Compare changes, previous / next ready frame and
exit; Escape leaves.
- Annotation categories: defaults plus the file's own with colours (`annotation.categories`,
`addCategory`, `editCategory`, `removeCategory`), `category` on annotations, coloured callouts,
a category filter and editor in the Inspect panel; stored backwards-compatibly.
- Shared widgets::icon_button / canvas_banner / dropdown_lead; has_status moved to the engine.
- Tests: devcompare_tests, devfocus_tests, annotation_categories_tests, doc handoff_tests, render
solo_tests, UI dev_mode_tests.

* M8: accessibility: screen reader names, keyboard navigation mode
- Screen readers: the custom-painted controls report a role, name, value and
state to AccessKit (number and text fields, dropdowns, segmented and toggle
buttons, tools with their keys, layer rows as tree items, pages, tabs, menu
items, the canvas describing the selection), from the shared widget helpers
and a `Tip` trait for ad-hoc icon buttons. Regions are named containers.
- Keyboard navigation: F6 / Shift+F6 (view.nextRegion / view.previousRegion)
cycle the toolbar, layers, canvas and properties; Tab / Shift+Tab move within
a region and wrap; Enter or Space activate; arrows move along the toolbar and
through the layer rows; menus and flyouts opened from the keyboard take it and
give it back; Escape returns to the canvas. A focus ring (new `focus` token)
shows until the next pointer press. Tab on the canvas selects the next layer
again instead of moving egui's focus to the tab strip; Enter that starts a
field edit no longer ends it.
- Reduced motion: pref.reduceMotion and the system setting (Windows
UISettings, macOS, GNOME, prefers-reduced-motion) turn egui's animations off.
- Contrast: light secondary and accent text meet WCAG AA.
- ui.inspect reports focus {region, keyboard, control} and reduceMotion;
ui.set {focusRegion}.

* M8: parity report command count after merging main
Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
* M8: accessibility: regression test against nested egui context locks
A debug build's temporary logging called the context inside a context closure and hung; the shipped code never does. Document the rule in a11y.rs and run every accessibility path with the AccessKit tree on, so a nested call fails the test (debug builds panic after 10 s) instead of hanging.

- Interaction editor: actions (top level and inside conditional blocks) reorder by dragging
their row's grip (list_drag, now also for lists shown in model order), one proto.action.move
per drop; the open action stays open where it lands; Escape cancels a row drag without
deselecting or closing what holds the list. The ... menu keeps Move up / Move down.
- Prototype expressions: `accent[Dark]` reads a variable's value in one mode of its collection
(Expr::InMode) and `mode(Theme)` is the name of the mode a collection is in where the
interaction runs (Expr::Mode); parsed, type-checked, displayed, stored by id (names accepted in
JSON), evaluated with the layer's modes. REST import maps VAR_MODE_LOOKUP over a variable and
one of its modes.
- Overlays opened through commands close on a click outside unless told not to, as in the editor.
- Collection::find_mode / current_mode replace repeated lookups.

* M3: components at scale; Alt-drag to swap instances
- Synthetic design system (engine `synthetic_ds`): ~300 components (icons; button, input,
card, nav and badge sets of size x state x type x theme variants), boolean/text/instance
swap/slot properties, instances nested four deep, text and paint styles, light/dark
variables bound across it, and 2,000 instances with overrides at every level.
- Propagation: value, size and added/removed-layer edits of mains reach their copies
directly; other edits rebuild each affected instance once, inner mains first; rebuilds keep
unchanged layers shared; bound variables no longer touch unchanged layers; auto layout
re-flows only where sizes or places changed.
- Fixes: values from variables (theme switches, bound radii) are no longer recorded as
overrides; a detached variable on an instance layer is an override that survives main
edits; exposed nested instances stay exposed; swapped nested instances keep their layer
names and the ids/overrides of layers their own main adds; renamed nested instances keep
their name when detached out.
- Instance swap properties have preferred values. `instance.swapAt` / `library.swapAt` and
Alt-drop from the Assets panel onto an instance swap it (highlighted while dragging).
- Instances pasted into other files follow their mains (library copies shared, published
components used from their library, other mains left behind as a missing main).
- Assets panel lays out only visible tiles and renders thumbnails lazily with a cache
invalidated per changed component; instance panel lists components once per revision.
- `figcraft-cli perf --instances`, UI frame bench and tests in components_scale_tests.

PDF export gains print options, saved on PDF export settings and taken
by file.export, file.exportLayers, file.exportFramesPdf, export.add /
export.update, figcraft-cli export and the MCP export tool:
- a bleed (points or a length like 3mm / 0.125in, up to 2 in) that grows
each page and shows what lies past the frame: its fills reach out to
the bleed edge and its children are clipped there instead; a print
page of one frame is trimmed to the frame's box;
- crop and bleed marks: 0.25 pt hairlines outside the bleed in
registration colour;
- MediaBox / BleedBox / TrimBox;
- CMYK colour: fills, strokes, text, gradient stops, images and
rasterised effects converted from sRGB with the naive, deterministic
K = 1 - max(R, G, B) formula; DeviceCMYK without an output intent (no
CMYK ICC profile can ship in the repository), soft masks stay RGB.
The Design panel shows a PDF row's print settings as a summary line that
opens them; the Export dialog has print options for its PDF preset.

SVG import comes in editable and looking right: groups named from their
ids with transforms baked into the layers (rotated, scaled and skewed
groups, viewBox scaling and <use> offsets used to be lost); rectangles,
ellipses and lines recognised and kept as those shapes; gradients with
exact handles, reflect/repeat and focal points; patterns as image fills;
clip paths and masks as vector, luminance and alpha masks; shadow and
blur filter chains as drop shadows, inner shadows and layer blurs; blend
modes; text as text layers (it used to vanish); images and nested SVG
images. What can't be represented is reported as import warnings
(file.import / file.open warnings, figcraft-cli info notes). Linked
files are never read, and documents nested too deep for the parser are
refused instead of crashing.
Pasted SVG is recognised after XML declarations, comments and doctypes
and lands centred in the view (file.import center). SVG export writes
vector masks as clip paths and alpha/luminance masks as the mask layer
drawn, so masks survive a round trip.
Tests: a corpus of 21 synthetic SVG files with hand-worked expected
pixels (158 probes), structure checks and export round trips; unit tests
for shape recognition, paints, filters, structure, mask export; hostile
input and byte-mangled corpus fuzzing; engine file command tests.

One keymap (figcraft_engine::keymap) now holds every default shortcut,
grouped like the public shortcut reference, with macOS and Windows/Linux
keys where they differ and canvas / text-editing contexts. The menus,
canvas, control channel, MCP key tool and Keyboard shortcuts panel all
resolve keys there; the catalog keeps only the menu tree.
- Fixed: Cmd/Ctrl+K made a link on the canvas (now Actions; link only
while typing), Shift+1 and Ctrl+Shift+? never matched (key names are
normalised), mask / bring to front / send to back / tidy up / layout
grids on Windows and Linux, distribute on macOS, outlines (Shift+Cmd+O),
pixel grid (Cmd+'), paint bucket B in vector edit mode.
- Added: Cmd/Ctrl+/, + and - zoom, Cmd/Ctrl+0, hold Z zoom tool
(view.zoomAt), two quick digits for exact opacity (object.opacityKeys),
Alt+Shift+U/S/I/E booleans, Alt+/ and Shift+/ remove fill/stroke, pixel
preview, Shift+E / Shift+D / Shift+Cmd+\ panel keys, Ctrl+Tab between
files (doc.nextTab / doc.previousTab), Shift+I, Shift+Space preview,
Home/End frames, Ctrl+C pick colour on macOS.
- Keyboard shortcuts panel: docked at the bottom, a tab per group, search,
keycaps per platform; tooltips show the platform's keys.

- Inner shadows paint over the fills and under the children and strokes, as documented (canvas,
PNG, PDF and SVG alike; text fills every run before the inner shadow and the strokes).
- Layer and background blur gain a progressive type: the radius ramps linearly from a start radius
at a start point to the end radius at an end point (unit-box points, like gradient handles).
Rendered by blending a few geometric blur levels, each blurred only around the pixels that use
it; bands and partial renders match one piece. Design panel type menu and Start/End fields,
on-canvas handles while the settings are open, effect.add/effect.set params, startRadius
variable bindings, scale tool, REST import (blurType, startRadius, startOffset, endOffset),
Inspect row; CSS leaves progressive blurs out.
- SVG export embeds renders for what filters can't match: noise grains over the vector layer
(crisp, blended), texture and progressive layer blur whole, background blur and glass from what
lies under the layer among the exported layers. PDF and SVG share the renderer's helpers.

While renaming a layer in the layers panel, Tab commits the name and
renames the row below (Shift+Tab the row above) and the selection
follows; Enter commits and Escape cancels without deselecting.
Cmd/Ctrl+R (object.rename without a name) renames the topmost selected
layer inline, opening its parents. The rename's field stays alive when
its row scrolls out of view. Ctrl now matches Cmd shortcuts off macOS.
The Inspect tab's empty-state hints wrap inside the panel.

- Expressions as text: Expr::parse (variables by name, literals, and/or/not, comparisons,
arithmetic, text joins) with plain-English errors, type checks for conditions and set variable
values; display reads back as the same expression.
- New commands proto.action.add/set/remove/move and proto.conditional.addBlock/setCondition/
removeBlock edit single actions by path, inside conditionals too; `expression` text accepted by
these and proto.interaction.add/set.
- Interaction editor: an action list (open, move, remove, add), Add action > Conditional, if /
else if / else blocks with a condition builder (variable picker, operator, value or variable) or
an expression field with inline errors, nested actions, set variable expressions.
- Presenter: hotspot hints toggle (Options menu, proto.presentOptions {hotspotHints}), hotspots from
the engine (proto_run::hotspots) and in ui.inspect; an Inspect panel showing the hovered layer's
properties ({inspect}).
- Fields keep the keyboard on the click that opens them, and the Enter that commits a field no
longer reaches the shortcuts.

Fill, stroke, effect and layout grid rows drag to reorder by their grip (a handle shows over the
row, an insertion line where it lands, the row's label follows the pointer like a dragged layer;
Escape cancels; lists that differ across the selection have nothing to drag). New commands
`fill.move`, `stroke.move` and `grid.move {ids?, from, to}` join `effect.move` (lists bottom first,
one undo step; items keep everything, linked list styles are unlinked).
Variable bindings on list items follow their items when a list is reordered or shrinks:
paint colours bind per paint (`fills/<i>/color`, `strokes/<i>/color`; `fill`/`stroke` stay the
first paint's), so a moved bound paint keeps its variable and its neighbours are never recoloured.
`fill.remove`, `stroke.remove` and `grid.remove` refuse negative indices.
Layout grids get settings in the Design panel (size; count, type, width or height, margin or
offset, gutter; colour) whose numbers bind to number variables (`layoutGrids/<i>/<field>`),
re-applied on variable and mode changes. Instance boolean and text properties bind to boolean and
string variables (`componentProperties/<name>`, from the instance's properties panel), kept across
instance rebuilds, following property renames and dropped on delete, reset and detach.
Inspect names the variable of each paint.

* M6: Dev Mode component code, annotations and ready for dev
- Component code: React (new), SwiftUI and Compose write components as reusable
units whose component properties are parameters (variant unions/enums,
boolean flags, text strings, instance swaps as views, slots as optional
content); variant sets share one definition (React: data-* rules for the
other variants); instances are calls passing only the values they change.
Escaped, unique identifiers. `inspect.componentCode` returns the parts.
- Annotations: notes with pinned properties on any layer, saved with the file
(left out when empty), undoable `annotation.add/edit/remove`, `annotation.list`
with live values; drawn as callouts on the canvas in the Inspect tab and
edited in its Annotations section. Instances keep their own annotations.
- Ready for dev: `inspect.readyForDev` lists frames and sections by handoff
status; the Inspect tab sets the status and lists them with a filter.
- Shared widgets: a multi-line field and the status dropdown are reused.

* M2: auto layout keyboard reordering, nested auto layout fixes, section hide contents and dev status
- Arrow keys move auto layout children one place: along the flow (past hidden and
absolute siblings), between wrapped rows, to the neighbouring grid cell, and into
the neighbouring nested auto layout frame; no undo step when nothing moves.
- Sections: section.toggleContents (hide contents), object.wrapInSection, frames in
sections are top-level frames (labels, flows, navigation, PDF export), navigating
to a section shows its frame shown last.
- Ready for dev turns "Changed" when contents are edited; dev.resolveChange with a reason.

Measuring (Alt/Option): distances from the selection to the hovered layer,
its parent (over the selection itself or empty space) and ruler guides;
Cmd+Alt for nested layers; containment both ways, overlaps between matching
edges, gaps with dashed extension lines; rotated layers and several selected
layers by their bounds; the measured box outlined. Alt while dragging shows
live distances to the neighbours (or the parent's edges); Shift+Alt reads out
an auto layout frame's padding and gaps. Labels are placed so they never
overlap each other or the size label and stay the same size at every zoom.
Commands: measure.distances, measure.padding.
Scale tool (K) canvas handles: one factor about the Scale panel's anchor
(tool.scaleAnchor, shared by the panel and the canvas; the opposite handle when
the anchor is on the side being dragged), Alt from the centre, flips past the
pivot, rotated layers and lines along their own axes, one undo step per drag,
a live factor in the size label and the pivot marked. scale_node now also
scales min/max sizes, layout grids, guides, fixed grid tracks, tiled images,
paragraph indent and run letter spacing.
Selection: Cmd/Ctrl-marquee selects nested layers, Shift-marquee toggles,
the context menu's Select layer lists every layer under the click
(select.layersAt), outlines are purple for every layer inside components and
instances, hover outlines show with the Scale tool too. Fixed marquees
selecting layers that only overlapped the marquee on one axis.

Pins follow their layers (to other pages too) and stay where they were
when the layer is deleted, re-pinned to the nearest surviving parent;
your pins drag onto another frame; crowded pins cluster when zoomed out
and a click zooms them apart; Shift+C shows or hides them.
Threads: edit and delete your own messages (marked edited), emoji
reactions, @mentions with a picker of the names used in the file (your
name from Preferences), read/unread state per name, and Copy link
(figcraft://comment/<id>; pasting it or comment.open goes to the page,
zooms to the frame and opens the thread).
Comments panel: search (text, names, frame), filters (open, resolved,
yours, unread), sort by date or page, each thread's frame and page,
Up/Down to step through threads. The presenter shows the presented
frame's comments (Comments button or Shift+C) to read and reply.
New commands: comment.react, comment.markRead, comment.open,
comment.next, comment.zoom, comment.link, comment.people,
pref.userName; comment.list gains filter/sort/query/frame, comment.move
re-pins. Old files load unchanged (the first message stays on the
comment; missing read state counts as read).

A bound fill or stroke colour now sets only the first paint's colour, keeping its opacity,
visibility and blend mode and the rest of the list (it used to replace every fill with one solid
paint). Effect bindings (`effects/<i>/<field>`) follow their effect when an effect is removed or
moved with the new `effect.move {ids?, from, to}`; removing a bound effect or the first fill/stroke
drops its bindings instead of passing them to a neighbour. `effect.remove` rejects negative
indices.

Right-to-left and mixed-direction names in the panels: layers, pages,
Assets, tab titles, the file header and canvas frame titles show in
visual order (Unicode bidi, joined Arabic letters, mirrored brackets),
elided at their end (the left end of a right-to-left name). egui shapes
each font run itself, so shown names are laid out a cluster at a time.
Rename fields keep egui's editing and draw the shown text over it: the
caret, selection, clicks, drags and arrow keys follow what's on screen.
System fonts are added for scripts the built-in UI fonts lack.
The Typography section's text style browser: list and grid views with
each style in its own font, search, folders, this file's and enabled
libraries' styles, apply, detach, edit the typography, create from the
selected chars, hover to preview on the canvas, and "Mixed" when the
chars use several styles. Text styles now link chars (style_id on text
styles), so a range can take a style; editing what a style sets
unlinks the chars edited; files from before link on open.
Live text previews (text.preview / text.endPreview): a hovered text
style, font style or named instance and a dragged axis slider show on
the canvas without an undo step; release commits one step, Escape
cancels. ui.input sends raw window input over the control channel.
Visual QA: list markers keep the paragraph's font, renames start with
the name selected and centred, Max lines shows while truncating.

Ruler guides can belong to a frame: `guide.add/move/remove/clear` take `frame` (as well as
`page`), keeping the guide in the frame's own coordinates. Frame guides move with the frame, span
only it on the canvas, are saved and copied with it, and snap the layers inside it. A guide dragged
out of a ruler and dropped on a frame becomes that frame's guide; its label shows the offset in the
frame.

- Background blur sees the whole backdrop under the layer: the renderer keeps the stack of
isolated surfaces it draws into (clipping frames, rounded clips, faded groups, masks) and
flattens it for the layer's area, reading past the layer's own box. A blur inside a clipping
frame now shows the frame's fill instead of the sharp layers below, on the canvas and in PNG
exports. The PDF export draws background blur and glass through the same code from a render of
what lies under the node (`backdrop::render_beneath`, which the PDF's backdrop now shares), and
its images match the PNG's pixels.
- Shadow spread offsets the outline: the shape filled and stroked twice the spread wide with
mitred joins (grow) or cut away (shrink), the stroked bands cached per outline. Ellipses stay
ellipses, stars keep sharp points, text keeps its letterforms, rounded corners grow their
radius. Inner shadows shrink the outline the same way. Canvas, PNG and PDF share the shadow
code; SVG writes spread shadows as the same geometry and now exports inner shadows.
- Glass effect (light angle and intensity, refraction, depth, dispersion, frost, splay): the
frosted backdrop bent towards the inside within `depth` of the edge, colour fringes, light on
the rim, from an exact distance transform with smoothed normals.
- Noise: mono, duo and multi colour modes, grain size, density, opacity and blend mode; grains
live in the layer's coordinates (stable when panning and zooming). Texture is now drawn
(pixels scattered by the radius, grain size, clip to shape).
- Design panel rows for noise mode/colours/opacity, texture clip to shape and every glass value;
`effect.add` takes `glass`; REST import of NOISE, TEXTURE and GLASS; Inspect rows and CSS;
the scale tool scales grain sizes, texture radius, glass depth and frost.
- Tests in new modules: render backdrop/spread/grain tests, PDF backdrop tests, SVG, doc,
engine and REST effect tests.

Pixel preview takes a resolution: `view.pixelPreview {scale: 1|2}` turns it on at 1x (one rendered
pixel per page pixel) or 2x (two, as on a high-density display); the canvas renders at that
resolution from a whole-pixel origin and magnifies it with hard edges once zoomed past it. The zoom
menu offers "Pixel preview 1x" and "2x" and now shows the on/off state of every view toggle.

- Responsive presentation: `proto.settings {responsive}` (saved in the
page's prototype settings). The player resizes the presented frame to the
device's screen, or without a device to its whole area at 100%, and lays
it out again exactly as an editor resize does (constraints, auto layout,
text; an axis the frame hugs keeps hugging), live as the window, device or
file change. The player keeps its design document and lays the screen out
from it each time (`cmd::proto::respond`). In the presenter's Options menu
(Responsive beside the size options, or Responsive / Fixed size on a
device) and the Prototype panel.
- Device colours: each device model lists its colour variants
(`proto.settings {color}`), drawn in code as the body's band round black
glass; screen corners are masked exactly. Colour picker with swatches in
the Prototype panel.
- Custom size: a bare screen of any size (`proto.settings {width, height}`
picks it), W/H fields and a swap button in the Prototype panel, imported
from REST `CUSTOM` devices.
- Library collections in the Design panel's Variable modes section, under
their library's name (`library.setVariableMode`; copies whose library
isn't read stay listed).
- Flow descriptions in the presenter's flow picker (and its hover) and under
each flow in the Prototype panel.
- Tests in new modules: engine proto_responsive_tests, ui-egui
proto_responsive_tests; REST device test updated.

PDF export
- Vector masks clip to the mask's outline, luminance masks are luminosity
soft masks (alpha masks as before).
- Background blur: the backdrop the page draws under the layer is rendered,
blurred and cut to its shape, under the layer's vector content.
- Text hyperlinks become clickable link annotations (one per line and link).
- Frames-to-PDF shares one path (`frames_pdf`): sRGB conversion for Display
P3 files, hidden frames left out, the file name as the PDF title.
- `figcraft-cli export -o x.pdf` and `convert x.figcraft x.pdf` write the
page's frames one PDF page each.
- Tests: mask types, backdrops, links, image deduplication, page sizes in
points, hostile inputs; CLI end to end. Checked by rendering the PDFs back
to PNG and diffing against the PNG export.
Prototyping
- Model: conditional actions (if / else if / else blocks), set variable mode,
and expressions (literals, variable references, + - * /, comparisons,
and/or/not, negate) for set-variable values and conditions; walk helpers
for nested actions (remap on paste, colours, destination checks, library
copies and pruning, canvas connections).
- REST import maps CONDITIONAL, SET_VARIABLE_MODE and SET_VARIABLE with
variable references and EXPRESSION values; unsupported functions (mode
lookups) skip the action with a warning.
- The presenter runs them in order (`figcraft_engine::proto_run`); the
Prototype panel summarises conditionals, edits set-variable-mode, and
`ui.set {protoEditor}` opens an interaction's editor.

- Transform box around 2+ selected points (Move tool): corners/edges scale
them (Shift keeps proportions, Alt from the centre), just outside a corner
rotates them (Shift: 15° steps, the box turns with them), dragging inside
moves them; one undo step each. Corners win over points, points over edges,
edges over segments.
- Commands: vector.edit.bounds, vector.edit.resize, vector.edit.rotate,
vector.edit.transform; object.flipH/V and the 90°/180° rotations act on the
selected points while editing (unless ids are given).
- Design panel in edit mode: W/H for the selected points next to X/Y (the
layer's dimensions are hidden while points are selected).
- Point snapping for dragged points and handles and both pens: points and
segment midpoints of this and other vectors, the usual layer targets and
the pixel grid, with guides and a marker on the point landed on; Ctrl/Cmd
turns object snapping off. Snap code generalised in snap.rs (Targets spans).
- Fix: handle/bend drags read positions in the gesture snapshot's coordinates,
so handles no longer lag when the preview re-fits the vector.
- Shared resize math (tools::resized_box) and handle hit-testing for layer
and point boxes; canvas draws both boxes through one helper.
- Tests in vectoredit/transform_tests.rs (incl. junk sweep for the
edit-aware commands).

A stroke can carry a width profile: widths at positions along the path
(each subpath by length), interpolated smoothly (monotone cubic).
- doc: WidthProfile / WidthPoint / WidthPreset (uniform, wedge, taper both
ends, eye, rounded, pinch) on StrokeProps, serde-defaulted so older files
load; paint reach and hit testing follow the widest point.
- pathops: path measuring by length and the variable outline (offset along
the normals, round/miter/bevel joins, caps, dashes keep their width,
Inside/Outside clip as before; bounded samples and dashes, uniform
fallback). Canvas, PNG, SVG (filled outline), PDF and outline stroke use it.
- engine: stroke.widthProfile {preset | points}, node.set widthProfile,
inspect output; the Variable width tool (Shift+W) in vector edit mode:
drag the path to add a width point, slide points, drag their handles,
Delete removes the selected one; vector.edit.widthPoint add/set/remove.
Every gesture is one undo step.
- UI: width profile dropdown with previews drawn in code and a flip button
in the stroke settings; the tool in the edit toolbar (new icon drawn in
code); width handles and a hover preview on the canvas; Position/Width
fields for the selected width point.
- Tests: profile maths, outlines, render regressions, tool gestures,
commands, exports and junk sweeps. ROADMAP, README, docs updated.

- Device rotation: phones and tablets turn to landscape (`proto.settings {rotation}`), saved in
the file and imported from REST files (`CCW_90`); the presenter and the preview pane size the
screen to the turned device and draw its body turned. A rotate toggle sits beside the device
picker in the Prototype panel.
- Presentation options: fit, fit width, fill and 100% (`proto.presentOptions {scale?,
deviceFrame?}`, an Options menu in the presenter, Z cycles them, R restarts), the device frame
shown or hidden, kept between presentations; what overflows the window pans by wheel or drag.
Presenter textures are capped to the GPU's limit (big frames at 100% no longer overflow it).
- Scroll momentum: drags fling and slow down exactly per frame-rate-independent sub-steps, the
wheel coasts after it stops, a drag past the ends stretches and springs back; repaints only
while moving, a press catches a fling.
- Variable modes in the Design panel: frames pick a mode per multi-mode collection, or Auto
(inherited); `variable.setMode {mode: null}` sets Auto.
- Tests in new modules (engine proto_present_tests, UI present_view_tests); docs and ROADMAP.
