/* =====================================================================
   te-invitamos.mx — landing (v3, Obsidiana)

   Negro cálido, oro y hueso; la tipografía de Marfil (Cormorant, Cinzel,
   Great Vibes, Lato). La página alterna dos franjas: `.dark` es el
   escenario —hero, universos, cierre— y `.light` es donde se lee. Todo
   componente pinta con las variables de su franja; ningún color directo.

   Sin JavaScript: el CSP no permite scripts y no hacen falta. El sobre del
   hero abre con un checkbox; las demos son animaciones CSS cuyo estado
   base es el estado final, así que con prefers-reduced-motion se ve la
   página terminada, quieta.
