The renderer lays every slide background over white (as PowerPoint does),
so a PNG export was always opaque. A new transparentBackground option leaves
the slide background out (both the white underlay and the background fill),
so only what is on the slide is drawn over transparency. Shapes filled with
the background (useBgFill) still show it.
- render: RenderOpts::transparent_background
- engine: file.export {transparentBackground} (PNG only; other formats
refuse it and write nothing), file.render {transparentBackground}
- UI: Transparent background checkbox in the Export dialog (PNG) and in
File > Export > Change File Type > PNG; the web download honours it
- CLI: render --transparent
- review.thesaurus's params doc parses under describe's grammar; describe's edit.copy test
expects the landing branch's {text, html?} answer.
- The Language dialog test picks the landing branch's "Français (France)" entry; the Format
Background test allows the pane's title to appear twice.
- Progress docs rebuilt from the landing branch's versions with land-r6's rows applied on top,
so the union merge no longer drops the pen-pressure, ui.pointer and ui.key rows.

Fix-up in the merge (review): a just-started stream gets 5 s for its first callback before it
counts as stalled (slow Bluetooth devices), and the failure count resets once a restarted
stream delivers, so one bad start no longer silences media for the session.

The Export dialog's GIF choice runs through SlideApp::export_as (desktop and web download),
.gif is a writable output extension for convert/run, and the CLI help pages describe GIF output
and --export-params. A file.export `slides` range string ("1-3,5") works for GIF as for PDF.

file.export's slide range and transition.sound's keys parse as parameters, and the subcommands
main added since #303 have their own help page.

- #178: ToUnicode ranges looked up without indexing
- #465: frame_num gaps are concealed (bounded) even when the SPS forbids them; cut streams keep playing
- #471: control request lines up to 256 MB so picture/media inserts still fit
- #473: a merge that loses its only row or column is removed, with regression tests
- #521: AutoCorrect no longer rewrites real words (cant, wont, im)
- #654: inherit_placeholder_geometry's doc comment back on its function

convert, run --save and run --export picked the format from the output
extension and fell back to native .deckcraft bytes for any extension
they didn't know, so out.odp, out.gif, out.svg and out.outline were
zips with exit status 0. They now fail before writing anything, with
the extension and the supported ones in the error.
Copy puts HTML on the pasteboard with the same plain words, so Pages keeps
bold, italic and underline, and a paste of that HTML keeps them here. A
shape with no text copies out as a picture.

A default export is 2 pixels per point. Without a resolution, Preview
treats those pixels as 72 dpi and the picture opens at twice the slide's
size. PNG pHYs and JPEG JFIF density now say scale times 72, so the
default is 144 dpi. Screenshots stay untagged.

DeckCraft forces X11 whenever DISPLAY is set. A stale DISPLAY (an ended ssh -X session, or
Xwayland turned off) made start-up fail with "failed to open display" while a Wayland
compositor was running. A local DISPLAY whose /tmp/.X11-unix socket is missing now starts on
Wayland when WAYLAND_DISPLAY is set; remote displays and live servers keep X11. Forcing Wayland
without a compositor keeps X11, and with no display at all the error says so plainly.

- ui.json / prefs.json are read through a new settings module: regular files only, 4 MiB
cap, parse errors logged, values sanitized (a saved zoom of 1e30 aborted start-up,
1e4 panicked in egui); writes are atomic.
- The canvas and the control protocol clamp stray zooms; the status bar shows the zoom in use.
- The canvas texture is cut to the GPU's max texture side (zoom 400% on a 2048 limit panicked).
- The system font scan opens only regular files of sane size (a FIFO named *.ttf in ~/.fonts
hung start-up), with depth and entry caps.
- AutoRecover skips non-regular entries and reopens at most 32 per start, newest first.

Times open, per-slide render, save, the PPTX round trip and PDF export, and
reports peak memory; xtask builds the CLI in release, runs it on the sample
and any given decks, and compares with docs/benchmarks/baseline.json.
deckcraft_pptx::import_theme reads the theme of a .thmx (its main document is
a theme part) or of a presentation's first master, with the media its format
scheme uses. design.browseTheme {path | name, data} applies it to the current
master as one undo step, giving the theme's pictures ids of this deck.
Design tab: Browse for Themes… next to the theme gallery and in the Slide
Master Themes menu; the desktop picker offers Office Theme (.thmx) and
presentations. Ribbon small buttons expose their label to accessibility (same
change as #512). Parity row Browse themes M → D.

The browser file picker only queued a name and bytes. When the read
finished, DeckCraft guessed the command and ran it on whichever
document and slide were active, so a picture, sound or outline could
land in the wrong place, and a later pick could finish first.
The request now keeps the document, the slide or master, the operation
and a cancellation id. A completion applies there, or is dropped when
that target is gone or the picker was dismissed.

The loopback control server spawned a thread per connection, read
unbounded lines, queued requests without limit and set no socket
deadlines. It now caps simultaneous clients (16) and request lines
(16 MiB), uses a bounded request queue (64) that answers busy when full,
closes sockets idle for 10 minutes or blocked on a write for 30 seconds,
and frees a connection slot whenever a client thread ends.

A cpal stream error was only kept and logged on stop, and the player kept
`streaming` true, so a device that died mid-play froze the voice and video.
AudioOut gains `failure()` (CpalOut reports DeviceNotAvailable), and
Player::tick also treats a stream with no callbacks for a second while a
voice plays as stalled. Either way the stream is stopped, voices continue on
the wall clock, and the next play retries the device; after three failures
the player gives up on the device and plays silently.

slide.new kept a leading tab as text, while text.set already turned it into a bullet level. The desktop --help flag was opened as a missing file.

Every transition and Effect Option was built in PowerPoint (COM), exported as
video and compared frame by frame with DeckCraft at the same progress
(mean abs diff over 150 variants 35.7 -> 15.0, 0-255).
- anim: transition_frame(kind, option, t, aspect) with measured curves
(smoothstep fades, ease-in-out moves, Cover/Uncover/Pan curves), directions
and option meanings, soft edges as per-corner opacity, 3-D effects as
perspective-projected cards, Dynamic Content moving slide contents over
cross-fading backgrounds (Source::OldBack/NewBack/OldContent/NewContent);
layer_mesh subdivides perspective quads so textures stay straight.
- New options: Page Curl Single, Glitter Hexagons, Shred In/Out, Zoom and
Rotate; PowerPoint-style Effect Options labels.
- render: composite_transition (CPU twin of the show), render_slide_part,
render_transition; deckcraft-cli render-transition FILE --slide N --t T.
- show: per-vertex opacity meshes, slide parts rendered once per transition.
- pptx: PowerPoint's elements and defaults (p:strips diagonal wipes, p14:warp
and p:newsflash for Zoom, p:zoom for Shape In/Out, glitter pattern, shred
rectangle/dir, prstTrans invX per preset, pageCurlSingle, defaults for
randomBar/doors/window/pan/zoom); PowerPoint reopens DeckCraft's files with
the same effects.
- Tests: measured curves, probes of which slide shows where at t, option
coverage, per-frame triangle budget, PowerPoint XML and defaults round trip.

--all names files slide-01.png onward, so --slide 8 on an 8-slide deck looked like an off-by-one. The index stays 0-based, matching slide.go, and the error now gives the range and the file names.

animation.remove's remark belongs to its `ids` option, so describe shows
it there instead of as a note on the whole command. A command with an
all-optional set of parameters is suggested as a bare id.
[claude-opus-5-5] on behalf of hoblin
A --cmd without a value now asks for COMMAND[=PARAMS]. The params field
says how describe reads it, table.split's row and col are optional as
the command reads them, and the MCP instructions name only shape
commands for `ids`.
[claude-opus-5-5] on behalf of hoblin
Same fix as storytold/gridcraft#117 (storytold/gridcraft#316): eframe drops
the window while AppKit's run loop still runs, AccessKit restores the
content view's class and AppKit's Touch Bar KVO observer throws on the
next display cycle. on_exit now ends the process on macOS once the
preferences are saved.
`deckcraft-cli help` and each subcommand's `--help` say what it does,
with a working example; `--help` never runs the subcommand. `describe`
spells out a command's parameters and what it acts on, `commands` lists
one command per line, and the MCP instructions say what format.* acts on.
[claude-opus-5-5] on behalf of hoblin
`deckcraft-cli render` took any argument it didn't recognise as the output
path, so `render deck.pptx --help` rendered the slide into a file named
`--help`, and a mistyped option was silently ignored. An argument starting
with `-` that render doesn't know is now an error naming it.
