/* Landing de Legal IA (Components/Pages/Home.razor + Layout/LandingLayout.razor).
   Se apoya en el Bootstrap recompilado con la paleta de marca; aquí solo va lo que Bootstrap no
   da: ritmo de secciones, tarjetas, botones, tipografía del landing y el reproductor diferido.
   Todo lleva prefijo lp- (o cuelga de .lp-root) para no afectar al resto de la app.

   Sistema visual: dos fondos que se alternan (blanco y .alt, un lavanda casi neutro) y el degradé
   de marca solo en tres momentos (.lp-tint: hero, "Qué incluye" y CTA final). Un solo radio, una
   sola sombra y un solo hover para todas las tarjetas. */
