   Paleta "Asfalto" (carbón con acento ámbar de señalización). Modo claro y oscuro.

   Todo color se define como variable en :root / [data-theme="dark"].
   Para personalizar un proyecto, cambia SOLO los tokens de la sección 1.
   El modo oscuro se activa con data-theme="dark" + data-bs-theme="dark"
   en <html> (Bootstrap 5.3 adapta formularios, tablas, modales, etc.).
