/* ===========================================================================
   allora — marketing site
   Palette and type are lifted straight from the app so the site and the
   product read as one thing:
     - shore gradient + blob tints from lib/features/auth/widgets/auth_background.dart
     - text / accent / divider from lib/core/theme/app_colors.dart
     - Pacifico wordmark from lib/features/auth/widgets/auth_brand_header.dart
   Fonts are self-hosted rather than pulled from the Google Fonts CDN: allora
   sells privacy, and a font request that ships every visitor's IP to a third
   party would undercut that on the front page.
