 - 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`, `pnpm showcase` writes the showcase catalog into `src/showcase.json` and `public/showcase` (both ignored): it downloads the commit `showcase.lock` pins, installs that commit's packages and runs its own validator, so a bad catalog fails the build; `dev` and `build` run it first, and `ELY_SHOWCASE=<checkout>` reads a local catalog instead. `pnpm test` runs the iso engine's, the mark's and the showcase list's tests, and `pnpm local` builds the gallery for localhost, builds the site and serves both on http://localhost:4173/ (wasm-bindgen and wasm-opt on PATH, as `scripts/web.sh` says). `node scripts/og.mjs`, with `pnpm preview` up, renders `public/og.png` from the hero and the header's mark. `node scripts/favicon.mjs` writes `public/favicon.svg`, which follows the system's mode, `public/apple-touch-icon.png` and the repo's `logo.png` (2048px, transparent) from the mark, in the colors `styles.css` sets. 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.
+- `cargo test --manifest-path compat/kit/Cargo.toml --target-dir target/kit` runs Ely beside GPUI Kit in one window: Tab through both, each library's dialog over the other's fields, one asset source. `scripts/check.sh` first resolves it afresh and holds `gpui-kit` to the newest release `cargo search` names, so a Kit release that moves its gpui pin fails resolution there, naming `gpui-pre`; Ely's pin then follows. Its lockfile stays out of git.

 - `scripts/icons.sh <lucide-name>...` adds icons. Then add a line to `IconName` in `src/primitives/icon.rs`.
 - `python3 scripts/countries.py <ne_110m_admin_0_countries.geojson>` writes the bundled world; `python3 scripts/tiles.py <same file>` writes the gallery's map tiles.
