   "Pulso de palacios": overlay full-screen (mobile) / modal centrado
   (desktop) que lista qué palacios del temario mnemo han tenido
   actividad en los últimos 30 días.

   Tono: CONTEMPLATIVO. No urgente, no alarmista. La paleta hereda
   el negro del proyecto pero el acento es azul-índigo (#5a7ba8) en
   lugar del ocre de Ágora — palacio = casa de estudio, no calle.

   Paleta base (coherente con style.css):
     #0a0a0a  fondo
     #141414  panel
     #e0e0e0  texto
     #5a7ba8  índigo (acento — sólo este módulo)
     #888     dim
