   medly.css — the app's design system, as CSS.

   Every value here is copied from medly_app/lib/app/theme/ so the website and
   the Android app are the same product rather than two that look similar. If a
   token changes in the app, change it here; do not invent a new one.

     colours  : app_colors.dart
     radius   : app_tokens.dart  AppRadius
     spacing  : app_tokens.dart  AppSpacing
     type     : app_typography.dart  AppText

   The app's brand note applies here too: the master plan proposes #0057B8, but
   both shipping apps, the store listing and the icon use emerald #059669.
   Emerald stands.
