   MedByte — Versión Web (SOBRE EL MOCKUP medbyte_web_lite).
   CSS extraído del <style> del mockup y adaptado:
     - Tema por sistema por omisión + interruptor (data-theme).
     - Fuentes locales (sin Google Fonts).
     - Primero móvil (≤768 px) sin tocar el diseño de escritorio.
     - Componentes nuevos por datos reales (carrusel, controles de video,
       fichas "Nuevo en MedByte", "Colegas en MedByte", pie legal, toast,
       estados de carga/error). Se conservan clases, colores y acomodo.
