 * Estilos del sitio público. Portados de la versión en Node (globals.css), con dos ajustes:
 *
 * 1. Al principio va el subconjunto del reset de Tailwind sobre el que se escribieron esos
 *    estilos: márgenes en cero, enlaces que heredan color, etc. Sin él el sitio se vería distinto.
 * 2. No hay estilos en línea —la CSP no los permite—. Lo que antes era style={{...}} en React
 *    ahora son clases: .tone-* para los colores de cada tarjeta, .hp para el campo trampa.
