/* BioMimic · diseño institucional de la UBO, común a todas las vistas: inicio, simuladores, panel docente, administración
   y sus pantallas de ingreso. Sigue DISENO-HEADER-FOOTER-UBO.txt (cabecera y pie, valores exactos) y
   DISENO-LOGIN-USUARIOS-UBO.txt (fondo, ingreso, cambio de contraseña y barra de usuario). Contenido propio de SAPIA.
   Lo institucional no cambia con el tema (cabecera blanca, pie oscuro, tarjeta de ingreso blanca); en el tema oscuro solo
   se oscurece el velo sobre la foto de fondo. Las variables llevan el prefijo --ubo- porque los simuladores ya usan --navy.
   Se publica en /ubo/ (ubo.css, ubo.js e img/) dentro de cada simulador; ubo.js oculta la cabecera al bajar. */
