/* ═══════════════════════════ Tokens de marca ═══════════════════════════
   Celeste y dorado (bandera + Sol de Mayo, como el logo): celeste es el
   acento de marca en general (nav, badges, íconos); dorado queda reservado
   para los botones de acción principal, para que el "sol" llame a hacer
   clic. El verde NO es de marca — se usa aparte, solo para éxito/activo.
   Outfit para títulos (geométrica, sin el aire "elegante" del serif de antes),
   DM Sans para el resto (la misma que ya usa el login del SaaS). */
