   Tema: blueprint oscuro. Diseño comprometido con una sola paleta.

   Reglas que no se rompen:
     · Solo se animan transform y opacity (van al compositor, no recalculan diseño).
     · Toda imagen lleva width/height en el HTML -> CLS = 0.
     · Sin @import, sin fuentes remotas: la CSP queda cerrada y no hay FOUT.
