   TrazaQR — Cabecera pública global (componente único reutilizado en toda
   trazaqr.com). El marcado del <nav> vive en partials/header.html y se
   inserta en cada página en tiempo de build (scripts/build-header.js) —
   ESTE FICHERO SOLO PONE ESTILOS, no genera ni inyecta HTML.
   No depende de las variables CSS de cada página (colores en literal) para
   que funcione igual en cualquier plantilla.
