   Proteïne per Euro — eigen componentlaag bovenop Tailwind (CDN)

   Let op: de Tailwind Play-CDN verwerkt géén @apply in externe CSS-bestanden,
   dus dit is bewust pure CSS. De kleuren hieronder komen 1-op-1 overeen met
   de tailwind.config in index.html.

   Stijl: papieren "sticker"-look met dikke inkt-outlines en vlakke kleuren —
   geïnspireerd op de outline-iconen in inspiratie.jpg (ei, melk, steak,
   biceps) en de zelfgeschreven titel in voorbeeld.jpg. Bewust geen
   glasmorfisme, geen zachte gloed en geen verlopen — alleen vlakke vlakken,
   dikke lijnen en één harde, verschoven schaduw als signatuur.

   Mobiel-eerst: alle raakvlakken (inputs, knoppen) zijn 56px hoog.
