 - Pictures: `image` 0.25 (MIT OR Apache-2.0), the crate gpui decodes with, default features off; it turns decoded frames and rims map tiles.
 - Maps: Natural Earth's 110m countries (public domain). `assets/maps/countries.geojson`, trimmed by `scripts/countries.py` to an ISO code, a name and positions to 0.01°, backs `maps::WorldMap`; the gallery's tiles are cut from the same file, z0 to z3, by `scripts/tiles.py` with Pillow.
 - Web: on wasm32, `web-time` 1.1 (MIT OR Apache-2.0) gives the `Instant` gpui's executor returns, std's own natively; jiff takes `js`, rust-embed `debug-embed`, similar `wasm32_web_time`. The gallery's web entry takes `gpui_web`, `wasm-bindgen`, `js-sys` and `web-sys` as wasm-only dev-dependencies, and a Hebrew cut of Noto Sans Hebrew 2.003 (OFL, `examples/gallery/fonts`): gpui_web asks the browser for emoji and CJK alone. The `wasm-bindgen` CLI at Cargo.lock's version and binaryen's `wasm-opt` finish the bundle.
-- Gallery: `examples/gallery`. Website: `frontend/` (Vite 8, pnpm), built after the components: a home page in motion with three.js and smooth scroll, and a components page with categories on the left and the chosen component on the right, after astryx.atmeta.com and gpui-kit.com. Each component runs live from the gallery built for wasm32 through gpui_web, in an iframe, never as a screenshot. It deploys to Cloudflare through `npx wrangler`.

 - `cargo run --example gallery -- --narrow 280 --capture <dir>` lays each page, header and body, at that width in a padded card and shoots it without its script, whose aims are measured at full width. Demos that set their own width run past the card.
 - `RUSTC_BOOTSTRAP=1 cargo check --lib --target wasm32-unknown-unknown` checks the web build; gpui_web's `wasm_thread` needs the bootstrap, as Zed's web examples do.
 - `ELY_GALLERY_ASSETS=<address of out/assets/> scripts/web.sh <out>` builds the gallery for the browser, profile `web`, and fails past Cloudflare's 25 MiB. It opens at `?page=<slug>&story=<title or slug>&theme=light|dark`; the host page calls `gallery.setTheme(mode)` or posts `{ ely: "theme", theme }`, before the wasm runs or after, and the page posts `{ ely: "ready" }` to its parent once it runs.
+- In `frontend/`: `ELY_GALLERY_ASSETS=<site>/gallery/assets/ pnpm gallery` builds the gallery into `public/gallery`, `pnpm dev` serves the site, `pnpm build` checks types and writes `dist`, `pnpm deploy` runs `wrangler deploy`. The site reads `examples/gallery/stories.json` for its chapters, stories and search.
 - `python3 scripts/stories.py` writes `examples/gallery/stories.json`, every page's sections in drawing order with their components, for the site: the names in a title, and in its `SHOWN` table what a story draws beyond them. It fails on a section opened inside another and on a ticked entry with a home of its own that no story names. `scripts/check.sh` refuses a stale one.
 - `cargo test --lib --features test-support`, `cargo clippy --all-targets --features test-support -- -D warnings`, `cargo fmt --check`. `scripts/check.sh` runs them with the house rules and lints the gallery for wasm32.
 - `rm -rf target/debug/incremental` and `cargo clean -p ely-gpui-component` after each task item keep the disk lean. Cargo keeps every old build of the crate and its tests under a new hash; by T25 they had filled the disk.

 - What cannot build for wasm32 is absent there through `cfg(not(target_family = "wasm"))`, never faked: the live terminal, `Terminal` and `Launch` with their grid, keys and search, and the gallery's capture harness.
 - A gallery demo a browser cannot run says why on the web through `ui::web_note`, in the blocked style: a second window (`own_window`), files from the dialog or a drop (`NO_FILES`), the menu bar, window moves.
 - A story is a gallery section: its title is a literal, one per page. Under `ui::Story` the one asked for draws without its title; the rest drop their demos (`ui::Section`), so nothing of theirs lays out, loads or moves. Their builders still run, so a demo that starts work on its own, a clock, a load or a shell, starts it through `ui::live`, which a story grants its own section alone and fails on a title no section has. A story the page lacks fails in the page.
+- Embedded in a page, the web gallery keeps gpui_web's hidden text field from taking focus, and hands focus back to the host, until a press or a key reaches it (`examples/gallery/index.html`); gpui_web focuses that field whenever its window is active. The host shows its own state until `{ ely: "ready" }`, sends the mode on ready and on every turn, and puts a skip link before the frame, since Tab inside gpui cycles within it.
 - The gallery's pictures go through `asset!` and `ui::picture` or `ui::resource`: a file natively, on the web an address under `ELY_GALLERY_ASSETS`, since gpui reads no files there.
 - On the web a paste reaches the focused field as the browser's paste event, through `EntityInputHandler::paste`, so Paste stays unbound there (`TextInput`, `CodeEditor`). Code that reads the clipboard itself awaits `read_from_clipboard_async`: gpui_web's `read_from_clipboard` answers at once and finds nothing (`tables::DataGrid`'s Cmd-V).
 - The first frame wears the host's mode through `Theme::set_mode_now`, a mode sent before the window opens included; `set_mode` fades from the colors on screen.
