   Se carga JUNTO a /home-v2.css (tokens, fuentes, header .pf-header, .pf-btn, .pf-techbar,
   .pf-wa-float — reutilizados tal cual, ya aprobados en producción). Este archivo solo añade
   los bloques de contenido de las landings comerciales. No modifica home-v2.css.

   Mismo lenguaje visual del Home V2:
   - hero sobre el degradado celeste de body.pf, fila superior tipo .pf-meta-*;
   - secciones crema #fbfaf4 con el MISMO stacking que .pf-story (fondo en ::before z:0,
     contenido z:4) para que la grilla de fondo siga visible encima del crema;
   - tarjetas blancas con borde var(--line) y radio 18px (como #catalogGrid);
   - títulos display con subrayado lima 40x3 (como .pf-story-title);
   - CTA verde lima con radio 6px (.pf-btn.primary).
   Sin JS para el contenido: todo el texto vive en el HTML. */
