Demos that open a second window, take files, move the window, read the clipboard or set native menus show a note on the web in the blocked style. 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.
