/* ===== Tokens de marca — Regla 8 de NEGOCIO.md (elegante, cálida, femenina
   sin excesos, sofisticada, minimalista, tonos beige/arena/crema) combinada
   con la paleta visible de Claude (claude.ai): coral/terracota + marfil cálido,
   para que la página tenga sinergia visual con la IA que enseña.
   Nota: esto es una aproximación a partir de lo que se ve en la interfaz
   pública de Claude, no un kit de marca oficial de Anthropic — si tenés
   acceso a sus assets de marca oficiales, lo ajusto para que calce exacto. ===== */
