   Grafito como base inmersiva, niebla como base informativa, verde salvia

   Revisión 2026-09-28: cortina «sintonizar», cursor propio, hero con ondas
   presentes y salida con scrub, galería de tecnología con título fijado y
   tarjetas que se acercan al centro, revelados de foto, grano, cabecera que
   se esconde, mando de dos densidades (solo con ?revision).
