   Papel frío, tinta casi negra y el oro del logo como único acento.
   Mobile-first. Breakpoints: 640px · 900px · 1100px

   Regla de forma (única para toda la web):
   - Todo lo que es "papel" (fichas, formulario, banner) lleva radio 2px.
   - Los botones son rectángulos con sombra dura desplazada que se hunden al pulsar.
   - Lo único redondo es lo que dibuja la mira del logo (círculos de fase).
