   COMPONENTE: Cómo comprar (página completa, app/Views/como_comprar.php)
   Guía paso a paso (timeline vertical) + tarjetas de info (envío/pago) +
   CTA final al catálogo. Contenido de lectura lineal, por eso el bloque de
   pasos se limita a un ancho de lectura cómodo en vez de ocupar todo el
   .container como hace la grilla del catálogo.
