/* ==========================================================================
   BMEN — sistema de diseño
   --------------------------------------------------------------------------
   Una sola fuente de verdad para colores, tipografía, espaciado y componentes
   de todas las pantallas propias de BMEN (paneles, admin, páginas públicas).

   La paleta sale del logo y no se inventa: marino (#102b4a, #1b3a5c, #0a1e34)
   y el trazo turquesa → cian (#5eead4 → #21c4df).
   Regla de uso: el marino estructura, el cian señala (activo, foco, enlaces).

   Temas: <html data-theme="light|dark">. El script de _tema_head.html lo pone
   antes de pintar: oscuro por defecto, o lo que la persona eligió con el botón.
   Sin JavaScript se respeta el modo del sistema.

   Las vidrieras de cada negocio (menú, quinta, barbería, gimnasio) NO cargan
   este archivo: usan el tema que elige su dueño.
