* perf(frontend): serve only the mdi icons the app uses @mdi/font ships a CSS rule and four font formats for every icon. Generate a trimmed stylesheet from the icons named in the source and alias the package import to it. - scripts/build-icons.ts writes src/plugins/materialdesignicons-trimmed.css (woff2 only, LF line endings, no source map pointer). predev and prebuild run it through build:icons, and CI checks the committed file is current. - scripts/trim-mdi-fonts.ts builds the allow list from src/, Vuetify's own icon set and the icons the backend names. Only a plain .mdi-name::before rule can be dropped; anything unsure is kept. - Custom notification icons the app does not draw fall back to the level icon instead of rendering blank. - An "All icons (mdi)" story under Primitives/RIcon shows every shipped icon with search, plus the icons that are available but not shipped. - Vitest keeps ?raw CSS imports instead of emptying them. - build:tokens leaves tokens.css alone when only formatting differs. Co-Authored-By: Claude Sonnet 5.5 <[email protected]> * perf(frontend): trim the mdi icon css in a Vite plugin Replace the generated, committed icon CSS with a transform plugin that trims @mdi/font in memory, in dev, Storybook and build. A watcher reloads dev when the source names a new icon. Drops build-icons.ts, the alias, the CI staleness check and the checked-in CSS. Co-Authored-By: Claude Sonnet 5.5 <[email protected]> * PR feedback * style(frontend): sort imports in notifications test Co-Authored-By: Claude Sonnet 5.5 <[email protected]> * perf(frontend): reduce the mdi icon trim to a build-only plugin Drop the icon browser story, the notification glyph probe, the build:tokens compare and the woff2-only font rewrite. The plugin now only removes unused icon rules in production builds, so dev serves the full set and needs no file watcher.
