T44d Web · What a browser cannot do says why; fonts resolve; the bundle builds

Demos that open a second window, take files, move the window, read the

IBM Plex Sans Regular joins the assets, unmodified, where gpui's svg
renderer loads it: gpui_web answers .SystemUIFont with it. The gallery's
web entry registers a Hebrew cut of Noto Sans Hebrew. scripts/web.sh builds
the bundle with wasm-bindgen and wasm-opt -Oz, 20.0 MB, and fails past 25 MiB.
