- Use existing MULTIPLIER_S/M/L from \$entities/Font in SliderArea instead
of inlining the 0.5/0.75/1 literals (constants already existed but were
duplicated at the call site).
- Centralize API base URL in \$shared/api/endpoints.ts (was duplicated
between proxyFonts and FilterAndSortFonts filters api).
- Promote every 'glyphdiff:...' localStorage key to a named module-level
STORAGE_KEY constant. Test files now import the source constant rather
than redeclaring it (eliminates silent-typo divergence risk).
- Use path aliases instead of relative paths
- Fixes module resolution errors when importing from other files
- Ensures fallback to Fontshare API works correctly
- Add gcTime parameter to TanStack Query config
- Add response validation in fetchFn with detailed logging
- Add fallback to Fontshare API when proxy fails
- Add USE_PROXY_API flag for easy switching
- Fix FontVirtualList generic type constraint
- Simplify font registration logic
- Add comprehensive console logging for debugging
Fixes: Query data cannot be undefined error
- Created src/entities/Font/api/proxy/proxyFonts.ts
- Implemented fetchProxyFonts function with full pagination support
- Implemented fetchProxyFontById convenience function
- Added TypeScript interfaces: ProxyFontsParams, ProxyFontsResponse
- Added comprehensive JSDoc documentation
- Updated src/entities/Font/api/index.ts to export proxy API
