/* ============================================================================
   NQ School - marketing site
   ----------------------------------------------------------------------------
   The palette, radii and card shell are lifted from the product itself so the
   site and the app read as one thing:
     - theme_color      #0369a1 (sky-700)   - manifest.template.json
     - background_color #082f49 (sky-950)   - manifest.template.json
     - card shell       bg-white rounded-xl border-gray-100 shadow-sm
                                            - components/ui/WidgetCard.tsx
     - semantics        rose / amber / emerald, violet as a minor accent
   The app is light-only (index.css paints body #fff and ships no dark mode),
   so this site commits to light as well. Every colour is painted explicitly,
   which keeps the page correct on a dark host ground.
