   Capa de presentación. No contiene lógica: todas las clases y atributos
   corresponden al marcado existente de las vistas Blade y a los ganchos que
   usan lms.js, course-menu.js, video-player.js, bulk-import.js,
   instrument-builder.js, course-configuration.js, module-panels.js y
   program-selection.js.

   Para cambiar la paleta, edita assets/theme.css (se carga después de este
   archivo). No hace falta tocar este archivo para ajustar colores.
