/* =========================================================================
   landing.css - la landing de gradoapp.cl (lo que ve quien no ha entrado).

   06-10-2026, pedido de Fernando: landing directa al estilo metamize.co. Sin
   VSL ni dolores: título y una sección por cada parte de la app (inicio, tutor,
   apuntes, exámenes reales, materia y plan), cada una con capturas REALES de la
   app animadas. En computador texto y pantalla alternan de lado; en celular van
   apiladas. La versión anterior quedó en scratchpad/landing.antes-1006-directa.css.

   Todo va bajo #landing para no tocar la app. Las animaciones parten cuando la
   sección entra en pantalla (landing.js le pone .on) y los textos aparecen con
   .rv.in (también landing.js).
