   PORTADA + INICIAR SESIÓN
   --------------------------------------------------------------------------
   Estructura replicada de la referencia que él pasó (el clon de la portada
   de Netflix, guardado en assets/textos/referencia-portada-login/):
   hero 100vh con formulario, filas alternadas, acordeón con radios, pie de
   4 columnas; login con caja translúcida sobre fondo.

   Acabados con los valores MEDIDOS en netflix.com (docs/NETFLIX-DISENO.md):
   rojo #E50914 (hover #B1060E, transición .25s cubic-bezier(.4,0,.68,.06)),
   superficies #232323/#2D2D2D, error #EB3942, texto secundario
   rgba(255,255,255,.7), botones radio 4px, tarjetas radio 8px, y la curva
   separadora bajo el hero. En vez de las carátulas de Netflix (que son
   suyas), el fondo es un collage con los pósters del catálogo de ELLA.
