/* =============================================================================
   Invitación web (extra de pago). Se aplica sobre rsvp.html cuando la boda la tiene activa.

   Dos capas independientes que la pareja combina:
   - Diseño (.tpl-*): fondo, ornamentos y marco de la portada.
   - Color  (.color-*): el acento (títulos pequeños, botones, ornamentos, cuenta regresiva).
   Ambas redefinen los tokens de styles.css, así el formulario de confirmación toma el mismo estilo.
   Contraste verificado: texto de acento ≥ 4.5:1 sobre los fondos; texto blanco en botones ≥ 3:1.
