   Design tokens, layout primitives, secciones del marketing
   site. Single-file CSS por simplicidad — si crece más allá de
   1500 líneas extraer secciones a archivos separados.

   Estructura del archivo:
     1. Tokens / variables CSS
     2. Reset + base
     3. Layout (container, grids)
     4. Primitivas (.btn, .badge, .card)
     5. Header / nav
     6. Hero
     7. Cómo funciona
     8. Antes vs Después
     9. Killer feature
    10. Features grid
    11. Product showcase (screenshots)
    12. ROI calculator
    13. Pricing
    14. FAQ
    15. CTA final + form
    16. Footer
    17. WhatsApp floating widget
    18. Animaciones
