* M6: REST import of prototypes and variables; export panel polish
REST API file JSON import now brings prototyping and variables along:
- interactions: on click/hover/press/drag, after delay, mouse enter/leave/down/up and key
triggers; navigate, open/swap/close overlay, back, scroll to, change to, open link and set
variable actions (lone unconditional blocks inlined); dissolve, smart animate, move, push and
slide transitions with easing incl. custom bezier and spring; the legacy transitionNodeID
- flow starting points (and the deprecated start node), overflowDirection, scrollBehavior,
prototypeDevice and prototype background
- the local variables response (collections, modes with the default first, values, aliases,
scopes), passed as `variables` to file.open / file.import (object, JSON text or path), found
next to the file (<name>.variables.json / variables.json) or embedded; boundVariables, paint
and text style bindings and explicitVariableModes map onto the fields variable.bind uses
- file.import appends variables, flows and prototype settings with the pages
- unsupported parts (video, gamepad, conditionals, variable modes, library variables) warn
Export panel: rows with a typed or preset size (2x, 512w, 512h), suffix and all five formats
through the new export.update command; export.add steps up (1x, 2x @2x, ...); a preview;
"Export N layers" through the new file.exportLayers (one file per setting, unique safe names)
in the panel and the Export dialog; file.export takes `size`. MCP open_file/export pass the new
params.

* M6: Inspect tab: properties with styles and variables, redlines on hover (#41)
The Inspect tab lists the selected layer's properties for handoff:
layout (size, position from the parent, rotation, opacity, radius), auto
layout (direction, gap, padding, alignment), typography, fills, strokes
and effects, each with the style or variable it comes from. Clicking a
value copies it. With the Inspect tab open, hovering measures distances
from the selection without holding Alt.
New command inspect.properties returns the same groups for agents.

Large documents stay interactive: the canvas re-renders only what a pan uncovers or an edit
touches, the layers panel lays out only the rows in view, and per-frame work no longer walks the
whole page.
- Benchmark: `cargo xtask bench [SIZES]` builds synthetic pages (`figcraft_engine::synthetic`:
screens with an auto layout header, a card group, button instances and shapes/text) at
1k/10k/50k layers and prints engine/render timings (`figcraft-cli perf --layers 1000,10000`) and
headless whole-UI frame timings (an ignored ui-egui test).
- Retained canvas rendering (`figcraft_render::Retained`, used by the render worker): views snap
to whole device pixels, so a pan shifts the previous image in place and renders only the
uncovered strips; an edit renders only where changed layers were and are
(`Document::changed_ids` diffs the two versions skipping shared structure; ancestors that paint
from their children's pixels - booleans, effects, masks - count whole; background blur reach
and noise are allowed for). Zoom, page, options, font or page-level changes, or large changes,
render the whole view as before. `ui.inspect` reports `canvas.renderWork`.
- The texture image is converted on the render thread, not the UI thread.
- Layers panel: only visible rows are laid out (stable ids while scrolling); rows are cached per
document version, page, expanded set and filter.
- Frame labels and layout grids of off-screen top-level frames are skipped; the Prototype tab's
connection sources are cached per document version.
- Text: the layout cache keys by a cheap fingerprint confirmed by `TextData` equality (no Debug
formatting per lookup, 32k entries) and hands out shared layouts; a layout generation marks
renders stale when fonts arrive. Overflowing text is culled by its glyphs, so it no longer
vanishes while its box is off screen.
Before -> after (release, Windows, 1440x900 view, ms; 10k / 50k layers):
- move one layer, re-render @100%: 7.65 / 6.49 -> 0.18 / 0.81
- move one layer, re-render zoomed out: 11.95 / 24.10 -> 0.16 / 0.77
- pan 40 px @100%: 7.53 / 6.82 -> 0.69 / 0.81
- pan 40 px zoomed out: 12.07 / 24.30 -> 1.62 / 4.17
- full render @100% / zoomed to fit: 7.78 / 44.22 -> 6.56 / 38.83 (10k @100%, 50k fit)
- UI frame, every screen expanded in layers: 6.16 / 39.07 -> 0.24 / 0.57
- UI frame, scrolling that panel: 6.11 / 40.18 -> 0.43 / 0.40
- UI frame, layers filtered by name: 1.03 / 6.92 -> 0.17 / 0.36
- UI frame, Prototype tab: 0.89 / 6.45 -> 0.18 / 0.80
- UI frame, idle: 0.31 / 1.43 -> 0.11 / 0.39
Unchanged and within budget: single-layer edits through the engine ~0.01 ms, normalize after a
one-node edit < 0.01 ms, hit test 26 / 93 us. Left: save/load at 50k (~0.7 s each), zoomed-out
renders at 50k (~40 ms).
Tests: retained renders match full renders after pans, moves, recolours, hide/remove/add, undo,
masks, overflowing text, edits under a background blur and an inner-shadow/noise layer, a drop-
shadowed group, and a blur panned in from the view's edge; zoom/page/options/page background
render full; junk views don't panic. Layer-row and prototype-source caches follow edits, undo,
page switches, expansion and the filter. `changed_ids`, the text cache, and the perf CLI.

- Cmd/Ctrl+V pastes an image from the system clipboard (screenshots, images copied in other
apps) as an image layer centred in the view; an image-only clipboard (no paste event) is
handled from the key.
- FigCraft remembers what it last put on the system clipboard (SVG of the copied layers, or a
marker): when the clipboard still holds it, paste uses our copied layers; anything newer from
another app (image, SVG, text) is pasted instead. Cut now also mirrors to the system clipboard.
- Desktop services read clipboard images (size-capped); the browser falls back to text.

- Versions now belong to the document (DocState.versions) instead of a process-global map keyed by
document uid, so they survive closing the file. A new, renamed or deleted version marks the file
as changed.
- .figcraft: `versions/index.json` (id, name, description, time, image hashes) plus one deflated
`versions/<id>.json` snapshot per version; images only versions use are stored once and kept with
them. Snapshots read from a file are parsed on first use (and written back as-is). Readers that
don't know versions ignore the entries; files without versions load unchanged. Damaged, missing,
oversized or duplicate entries are skipped and reported, never failing the load. At most 100
versions per file; names and descriptions are clipped.
- Commands: `file.saveVersion {name?, description?}` returns the version; `version.list`;
`version.restore {id | index}` (one undo step, keeps the file name, stays on the current page);
`version.rename {id | index, name, description?}`; `version.delete`; `version.duplicate` (opens
the snapshot in a new tab). Indexes are validated: a negative index used to restore version 0.
`req_index` param helper shared with the guide commands.
- Version history panel in the left sidebar in place of Pages and Layers (File > Show version
history; Save to version history opens it with the form): save form (title, description),
"Current version" on top and the versions newest first on a timeline with name, relative time and
description; per-version menu (also right-click): Restore, Rename (title and description inline),
Duplicate, Delete (confirmed inline). New shared `widgets::button`.
- `figcraft-cli run --out x.figcraft` keeps the version history.

- New `figcraft_format::rest`: imports the public REST API file JSON (`GET /v1/files/:key`, and
the nodes endpoint's response) using the published reference only. Pages (name, background,
flow starting points), the layer tree, names, visibility, lock, opacity, blend mode, masks.
- Geometry from `relativeTransform` (children of groups/booleans checked against
`absoluteBoundingBox` to settle their space), else absolute bounds + rotation; sizes, corner
radii (uniform and per corner), smoothing, clip content, constraints, export settings, layout
grids.
- Paints: solid, linear/radial/angular/diamond gradients (handles map 1:1), image fills (fill,
fit, tile, stretch, rotation, filters) with bytes from a resolver or a grey placeholder keyed by
the imageRef; paint opacity, visibility and blend. Strokes: weight, per-side weights, align,
caps, join, dashes, miter angle. Effects: drop/inner shadow (offset, radius, spread, show behind),
layer and background blur.
- Vectors from `fillGeometry` (stroke-only vectors use the `strokeGeometry` outline), ellipse arc
data, stars/polygons, boolean operations. Text: characters, type style (family, style or weight
+ italic, size, line height px/%/auto, letter spacing, case, decoration, alignment, auto resize,
truncation, paragraph spacing/indent, OpenType flags, links), per-character overrides → styled
runs (UTF-16 aware), list type.
- Auto layout: direction incl. grid, alignment, padding, gaps, wrap, hug/fixed/fill sizing (legacy
and per-axis fields), absolute positioning, min/max, grid cells.
- Components and sets with descriptions and property definitions (names lose their `#id`
suffix); instances of components in the file become instances with their property values and
listed overrides; outside components and component cycles stay frames. Shared styles are created
from the layers that use them, named from the metadata.
- Unknown types and fields are skipped with a counted warning list; sizes, depth (256), layer count
(200,000), path length and list lengths are capped; nothing panics on junk.
- Engine: `file.open` / `file.import` / CLI detect the JSON by content, link imported instances to
their mains (sources and overrides), read image fills from an `images` folder next to the file,
never save over the JSON, and return `warnings`. `file.import` now remaps ids across all
imported pages at once (instances keep their main and layer sources) and brings styles and page
backgrounds along. `figcraft-cli info` prints load notes.
