   galeria.css — Galería Acambuco (carrusel + subida a Storage).
   Máquina visual portada del "Centro de Recursos Visuales" (Departamento
   Médico, sección #carrete) y adaptada a Acambuco.
   - Prefijo propio gal-* / --gal-* para NO colisionar con dm-* ni styles.css.
   - Self-contained con tokens propios (--gal-*), igual que notes-wall.css:
     no depende de variables de styles.css.
   - Etapa 1: carrusel (viewport/track/slide/imagen, prev/next, dots),
     info (título/autor/fecha), modal "Agregar imagen" y modal de borrado.
   - Comentarios y likes: NO se maquetan en Etapa 1 (van en etapas 2 y 3).
