   VIOLETTA SOFTWARE — NAVBAR (2026-08)
   ---------------------------------------------------------
   Se carga desde el esqueleto DESPUES de los estilos de cada
   vista, para que la barra sea identica en todas las paginas.
   Sustituye al bloque .navbar de violetta_ui.css.

   Problemas que resuelve:
     - El menu movil nunca funciono: violetta_ui.css ya definia
       .navbar-links.active pero no habia JS que la aplicara.
     - Sin estado activo, no se sabia en que pagina estabas.
     - La pildora flotante se salia del ancho en pantallas
       pequenas y tapaba el contenido al no reservar espacio.

   vuelve transparente y clara sobre el video; al desplazar se
   condensa en la pildora, que ya cae sobre fondo claro.
