/* ============================================================================
   SKIN CDMX — v2 (rediseño del hero, marco tipo timbre postal)
   ----------------------------------------------------------------------------
   Aditivo, NO toca GDL. Todas las reglas viven bajo `body.sede-cdmx`.
   Si el toggle quita esa clase, el hero se ve "limpio" (base GDL).

   Cómo está montado el marco (de fuera hacia adentro):
     .hero            → fondo mostaza (es el sello completo)
     .hero::after     → perforaciones (medio-discos color papel sobre el borde
                        exterior, dejando dientes de mostaza entre muescas)
     .hero__paper     → papel crema con textura envejecida (inset = ancho de la
                        banda mostaza visible alrededor)
     .hero::before    → estrellitas azules dispersas sobre el papel
     .hero__inner     → contenido + borde rojo interior (::before)

   Variables de control:
     --tr   radio del diente de la perforación   (11px mobile / 14px desktop)
     --tg   paso entre dientes                   (22px / 28px)
     .hero__paper inset  = ancho de la banda mostaza (20px / 28px)
