/* ============================================================
   ENIGMA — sistema visual (v3, referencia "enigma-ui-reference-v2")
   ------------------------------------------------------------
   Papel cálido, tinta de alto contraste, un rojo ENIGMA solo para
   acciones principales y lo activo en la navegación. Dentro de los
   tableros la interacción usa --sel (petróleo): el rojo ahí se leería
   como error.

   Tipografía
     --font-display  Source Serif 4 — titulares (editorial).
     --font-ui       Geist — interfaz y texto.
     --font-num      Geist Mono — cronómetros y cifras tabulares.

   Disposición: barra lateral fija en escritorio (se reduce a un riel
   de iconos en las páginas de juego), cajón + pestañas en móvil.
   Alias antiguos (--paper, --ink-soft, --line-strong) para los
   motores de juego.
