/* ---------------------------------------------------------------------------
   Sistema de Bingo — capa de identidad visual.

   app.css define la estructura (layout, tamaños, comportamiento responsive).
   Este archivo define cómo se ve: color, tipografía, elevación y estados.
   Separarlos permite rediseñar sin tocar la maquetación.

   Reglas de la casa:
   - Ningún componente trae un color fijo: todo sale de las variables de abajo,
     así el tema claro y el oscuro comparten una sola estructura.
   - Contraste mínimo AA (4.5:1 en texto, 3:1 en bordes de control).
   - Las animaciones usan solo transform y opacity, y respetan
     prefers-reduced-motion.
