/* ===========================================================
   Bitware — sito di presentazione

   Palette costruita sull'indaco #5460b5: è il colore che l'app
   AnyWhen assegna al gioco Timeline (Palette.brandFill in
   mobile/lib/src/theme.dart), con #4b57a8 come chiusura del suo
   gradiente. Lo stesso valore torna più in basso come --aw-indigo,
   nella pagina dell'app.

   Anche i neutri sono virati sullo stesso blu invece di essere
   grigi puri: il nero-e-grigio preso dal logo, da solo, dava al
   sito un'aria troppo severa.
