The web shell queues the page's calls as control requests (the channel the desktop control server uses) and answers them on the next frame. The API is installed in every mode; opening, saving, the file name and the unsaved flag stay with the host messages.
wasm32 cannot allocate a Vec of 2 GiB (isize::MAX is one byte less), so
the open check that only rejected a larger file trapped on that boundary.
Refuse 2 GiB as well, and say so in the failure the host receives.

The transports, the message types and the origin checks come from the shared crate (storytold/craft-libs#420). `data-host="page"` on the canvas now hosts DeckCraft in a page's own document, as in the other apps; the parent bridge keeps its behaviour.
A file the page sent without a name opens untitled and unchanged, like the
empty start presentation, so the page's next file closed it. Host mode now
records the start presentation (start_for_host) and only the first file
that opens takes its place, as packaging/web/README.md says.
Save As > Save under the presentation's own name changed neither the path
nor the dirty flag, so the Save As page stayed open and a second click sent
the file again. The page now also compares the revision, which every save
bumps.

A same-origin page that frames DeckCraft's web build with ?host=parent
sends a file with deckcraft:open and gets every save back as
deckcraft:save {name, saveAs, bytes} instead of a download, with
deckcraft:ready, deckcraft:dirty and deckcraft:failed, as GridCraft,
WordCraft and PdfCraft do. Without ?host=parent nothing changes.
Save follows the desktop app. Every file from the page opens through
file.adopt like File > Open on the desktop; a presentation sent with a
presentation name keeps that name as its file, so Save (Ctrl+S, the
File tab, the Close prompt or the command palette) writes it back under
that name and format with saveAs: false. Anything else (no name, an
outline, a damaged file opened as a repaired copy, a dropped file) is
untitled, and its first Save is a new <title>.deckcraft with saveAs:
true, as is Save As. Exports and Print are copies (saveAs: false).
Host mode starts with an empty presentation that gives way to the first
file while untouched, &author= signs comments, and the URL flags are
read as whole parameters so a free-text author can't set ?show.

* egui037-20261022: migrate DeckCraft to egui 0.37
Preserve current-main document and PDF behavior alongside the reviewed input, capture, font, ribbon and notice-packaging migration.
Validation: cargo xtask ci passed all eight stages, with 1,877 workspace tests and three doctests passed, six tests ignored, strict native lint and 23 WASM crates checked. Native GUI, platform and performance qualification remains separate.
* E21: restore Latin coverage and enforce required font inputs
* Fix migration review findings in font validation and UI controls
* M-egui037: document UI lifecycle and regression contracts
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.

There was no way to turn a presentation into an animated GIF. file.export now writes one: format
`gif` (or a .gif path), one frame per slide drawn by the slide renderer and shown for
secondsPerSlide, encoded with the `image` crate's GIF encoder (already a dependency, no new
crates) with a 256-colour palette per frame: exact when a slide has 256 colours or fewer,
NeuQuant otherwise. Slides are composited onto white.
Options: width (small 640, medium 960 (default), large 1280, extraLarge 1920, or 16-3840 px; the
height follows the slide's aspect ratio, no side over 3840), secondsPerSlide (0.1-600, default 5,
written in GIF hundredths), loop (forever by default, or once: no NETSCAPE2.0 block), slides (a
list of indices, in play order) and includeHidden (hidden slides are skipped by default).
Out-of-range or wrongly typed values, NaN and infinities are BadParams errors, never panics; at
most 500 frames and 200 million pixels in total, checked before anything is rendered.
- Engine: crates/engine/src/gif_export.rs (options, frame list, size, encoder);
cmd::file::gif_bytes, save_bytes("gif"), format_for_path(".gif").
- UI: the Export… dialog (Command palette; the app has no File menu yet) gets "Animated GIF (.gif)" with Size, Seconds per slide, From/To slide,
Loop forever and Include hidden slides; an invalid range or value keeps the dialog open with a
message. The web build downloads the bytes (image/gif).
- CLI: convert IN OUT.gif, run --export OUT.gif --export-params JSON; usage lists the format and
options.
- MCP: the export tool lists gif and width/secondsPerSlide/loop (slides and includeHidden now
apply to PDF and GIF).
- Docs: file-format parity GIF row, gaps (video export remains), parity checklist row M -> P
(P2 breadth 36% -> 37%, overall 79%), control protocol, MCP, README, ROADMAP progress log.
Transitions and build animations are not animated in the GIF (tracked with video export).
