wasm32 can't catch a panic, so the command and frame guards do nothing in the browser and a panic ended the page with its unsaved changes. The page now follows its files with unsaved changes after every frame; its panic hook writes them to local storage as .figcraft copies (as many as fit) and says on the page that it stopped. The next page opens them again as unsaved files: file.recover also takes the copy as base64 data. The recovery-copy helpers move from the desktop app into figcraft_engine::branches so both share them.
The browser build's wasm was 25,982,540 bytes, past the gate raised for 0.12.1. It is now
23,915,213 bytes (22.8 MiB), 1.2 MiB under the restored 24 MiB gate:
- Catalog rows keep their plural forms behind a reference: Text is two words, not room for
four strings, across ~52,000 baked-in rows (-454 KB).
- The browser build compiles with wasm SIMD (apps/figcraft-web/.cargo/config.toml, wasm-opt
--enable-simd), so egui's glyph rasterizer leaves out its scalar SIMD fallback (-1.6 MB).
The plugin workspace is built from the repository root and stays without SIMD.
- Revert the gate raise (cb227c97); the hosting guide names the WebAssembly SIMD requirement.
Windows narrower than 760 pt show the Layers or Design panel over the canvas, opened from two
touch-sized buttons. Two fingers pan as well as pinch. The main toolbar pill is capped to the
canvas width and scrolls sideways (drag or wheel) when its buttons don't fit; the help button
moves above it when they would overlap. The web page's viewport covers the safe area and stops
touch scrolling and overscroll.

The 0.3.0 web release failed packaging/web/package.sh's 24 MiB gate: the wasm grew from
22.2 MB (0.2.0) to 27.0 MB once the plugin sandbox (wasmi + wasmparser, #101) and the
collaboration crates (#103-#105) joined the browser build, which still used the desktop
`release` profile (opt-level 3, thin LTO, 4 codegen units).
- Cargo.toml: new `web-release` profile (inherits release; opt-level "s", fat LTO, one codegen
unit, no debug info, stripped). opt-level "z" measured 16.9 MB; "s" keeps render speed.
- apps/figcraft-web/index.html: build with that profile, and pass the wasm features rustc emits
(bulk memory etc.) to wasm-opt, which otherwise rejects the size-optimised module.
- Version 0.3.0 -> 0.3.1. docs/releasing.md: the web profile and size history.
