/* ==========================================================================
   Caso Carolina Herrera (/casos/carolina-herrera/), 24/10/26.
   Sobre el motor común (assets/css/ma-caso.css). Lo propio: las bandas de color del seminario que se alzan
   como paneles de desfile y descubren la casa; la paleta que crece al bajar; las piezas y los podios que
   pintan la página con su color; las tres salas a pantalla completa; Good Girl Murano, que se ilumina como
   un foco en una sala a oscuras; la sala preparada que se llena; la web en navegador y en móvil, y las
   películas de Vimeo, que solo se cargan al pulsar. Prefijo ch-.
