   Caudal · Fontanería — demo WhiteMoon
   Tema "agua profunda": azul marino, azul agua y ámbar de urgencia.

   CONTRASTE: lo mide scripts/verifica-contraste.py (pares planos de la
   paleta + el peor píxel real bajo el texto del hero). Reglas de uso:

     - Sobre claro (#ffffff / --bg2) el texto en color va SIEMPRE en las
       versiones profundas: --b-dark, --b-deep, --a-deep, --urg.
     - --b (azul agua) y --a (ámbar) nunca pintan texto sobre claro: solo
       fondos, bordes y detalles.
     - El botón ámbar lleva tinta oscura (--text): 9.63:1. Texto blanco
       sobre ámbar no se usa en ninguna parte.
     - Sobre marino el texto va en --on-dark / --on-dark-muted, y el acento
       en --a o --b-sky.

   Breakpoints: 900px y 600px.
