  Gemeinsames Stylesheet für buddiq.app (alle Seiten verlinken /site.css).

  Design-Quelle ist die App:
    Farben  → lib/theme/app_theme_colors.dart (AppThemeColors.light/.dark)
    Radien  → lib/theme/app_radii.dart
    Schrift → Instrument Sans wie lib/theme/app_theme.dart, Typo-Skala wie
              lib/theme/app_text_styles.dart (32/700, 24/700, 20/600, 16/400, 14/600, 12/400)
  Ändert sich die App-Palette, hier nachziehen.
