   CRILLÓN · WEB MARKETING PATTERNS
   Patrones específicos del marketing site (Home, fichas de proyecto,
   ficha de barrio). NO forman parte del design system core — un deck,
   una app interna o RRSS no deberían importar este archivo.

   Estructura:
   1. Nav fija con scrolled state (backdrop-blur)
   2. Hero con video + overlay graduado (light/medium/deep)
   3. Stats band con divisores verticales
   4. Editorial split (5/7) con caption sobre imagen
   5. Project card asimétrica (lg/md/sm)
   6. Filter bar (chip pills)
   7. Pillars grid (sección oscura "Why")
   8. CTA strip + Footer
