     derecha:   form blanco con CTA gradient + glow
   Mobile: hero pasa a banda superior reducida.

   Tokens consumidos: --brand-primary/secondary/accent (Knauf overlay
   los ha sobreescrito ya), --gradient-knauf-full, --font-family-mono,
   --danger, --text-tertiary.

   El logo se aplica filter: brightness(0) invert(1) para renderizarlo
   blanco sobre el fondo azul. Si el cliente entrega un logo blanco
   propio, eliminar el filter.
