/* Urocuyo Academy — Residentes de Urología
   Hoja de estilos compartida por la landing de Residentes, las 14 páginas de
   módulo y la plantilla de clase. Reutiliza exactamente los tokens de marca,
   tipografías y componentes (header, footer, badges, tarjetas) ya usados en
   el resto de Urocuyo Academy (Inicio / Estudiantes). No se tocó ningún
   archivo de Estudiantes para construir esto. */
