/*
  Font Awesome ya NO se carga aquí con @import (eran 5 archivos
  encadenados y bloqueantes: fontawesome, brands, solid,
  sharp-thin, sharp-duotone-thin — mucho más lento y frágil).
  Ahora se carga con un solo <link> en el <head> de cada página
  (ver index.php, login.php, etc.), con el paquete "all.min.css"
  que ya incluye solid + brands + regular.
