   Traza OTR — portada pública (index.html)
   ───────────────────────────────────────────────────────────────────────────
   Es la puerta de entrada del sistema: presenta el producto y desde aquí se
   inicia sesión. El sistema en sí vive en app.html.

   No usa los tokens de css/tokens.css salvo las tipografías: tokens.css está
   calibrado para la aplicación (superficies claras, tablas, formularios densos)
   y esta página tiene otro registro — héroe oscuro, vidrio, texto grande. Se
   carga igual porque de ahí salen las @font-face de Sora y Manrope, que van
   autoalojadas: en faena no hay señal para bajarlas de Google.

   Las variables llevan prefijo --lp- para no chocar con las de la aplicación.
