/* ════════════════════════════════════════════════════════════════
   pricing-section.css — Sesion 54: bloque reutilizable de planes
   ════════════════════════════════════════════════════════════════
   3 sub-secciones autocontenidas:
     1. Cards de precios (3 variantes coloreadas + asterisco IVA)
     2. "Cada semana recibiras" (3 cards con dot)
     3. Garantia + Pago seguro (compacta, 1 fila)
     + Modal signup (overlay con form)

   - Sin dependencias externas mas alla de Google Fonts (IBM Plex
     Serif + Inter). Se asume que la pagina anfitriona ya los carga.
   - Self-contained: todas las variables corporativas se definen
     localmente en .pricing-section, sin depender del :root de la
     hoja global.
   - Mobile-first: <=640px / 641-1023px / >=1024px.
   - prefers-reduced-motion: respetado.
