+// Localize external Google Fonts (fonts.gstatic.com) references in Flutter Web build output.
+//
+// Usage (post-build):
+//   # Run AFTER: flutter build web --no-web-resources-cdn
+//   dart ../../.github/workflows/scripts/flutter_local_font.dart
+//
+// What it does:
+// In main.dart.js:
+//    - Find any referenced resources under: https://fonts.gstatic.com/s/
+//      (including the common pattern where Flutter concatenates the base URL with a relative path)
+//    - Download them into: build/web/assets/gstatic/<path>
+//    - Rewrite "https://fonts.gstatic.com/s/" -> "assets/gstatic/" so runtime loads locally
+//    - Only download font subsets needed by supported locales (parsed from message.dart)
+//
+// Notes:
+// - This script DOES NOT call `flutter build web`. It only patches the output.
+// - This is a best-effort post-process. Always verify in browser devtools.
