/*
 * tdc-base.css  —  Tarjetas Digitales Chile (tema dark / NFC)
 * ------------------------------------------------------------
 * Fundaciones del SITIO PÚBLICO: design tokens, reset, tipografía,
 * botones, formularios, alertas, container y páginas CMS/404.
 *
 * IMPORTANTE: este tema es SOLO para el front (lo carga lib/layout.php).
 * El admin sigue usando base.css + components.css + admin.css (tema claro).
 * No hay choque porque admin y público cargan archivos distintos.
 *
 * El único "knob" de marca es el par de acentos --a1 / --a2 (abajo).
 * Cambiarlos retematiza todo el sitio.
