/* ---------------------------------------------------------------
   Tier Cards (PricingThree), la sección de precios de Scrolltide
   (sep-2026), portada sin React para Programas y Matrícula del sitio
   Marca. Es la plantilla tal cual: el mismo lienzo de 1600x900, las
   mismas capas de luz y las mismas tarjetas de vidrio. El azul
   profundo del original ya es el navy de la marca, así que no se tocó.

   Lo que cambió, y nada más:
   - SectionFrame es CSS más un ResizeObserver (tier-cards.js).
   - El logo es el rombo Tesla y la ficha de «cerrar», que no hacía
     nada, lleva de vuelta al inicio.
   - Bajo 1024 px el lienzo se suelta y las tarjetas se apilan: escalado
     entero, en un celular el texto quedaría en 4 px (la plantilla lo
     dice: «give narrow screens a different treatment»).
   - Todo va dentro de .tier, así .frame y compañía no pisan al sitio.
