# Description of Changes
This PR refactors the frontend icon system to remove reliance on
@mui/icons-material and the Google Material Symbols webfont.
🔄 Changes
Introduced a new LocalIcon component powered by Iconify.
Added scripts/generate-icons.js to:
Scan the codebase for used icons.
Extract only required Material Symbols from
@iconify-json/material-symbols.
Generate a minimized JSON bundle and TypeScript types.
Updated .gitignore to exclude generated icon files.
Replaced all <span className="material-symbols-rounded"> and MUI icon
imports with <LocalIcon> usage.
Removed material-symbols CSS import and related font dependency.
Updated tsconfig.json to support JSON imports.
Added prebuild/predev hooks to auto-generate the icons.
✅ Benefits
No more 5MB+ Google webfont download → reduces initial page load size.
Smaller install footprint → no giant @mui/icons-material dependency.
Only ships the icons we actually use, cutting bundle size further.
Type-safe icons via auto-generated MaterialSymbolIcon union type.
Note most MUI not included in this update since they are low priority
due to small SVG sizing (don't grab whole bundle)
