## Build the gallery
`ELY_GALLERY_ASSETS=<address>/ scripts/web.sh <out>` builds the gallery with the `web` profile, runs `wasm-bindgen` and `wasm-opt -Oz`, and copies its page and pictures beside it. It needs the `wasm-bindgen` CLI at the version in `Cargo.lock` and binaryen's `wasm-opt`, and it fails when the wasm passes Cloudflare's 25 MiB. `ELY_GALLERY_ASSETS` is the address the pictures are served from, ending in `/`: GPUI reads no files in a browser.

The gallery opens at `?page=<slug>&story=<title or slug>&theme=light|dark`. A story needs its page.
