/* =====================================================
   LUMINA.CSS — solo se carga en lumina.html
   Requiere main.css cargado ANTES:
   <link rel="stylesheet" href="../../main.css">
   <link rel="stylesheet" href="lumina.css">

   Reglas de convivencia con main.css:
   - NO redefine: reset (*), html, body, a, ::selection,
     scrollbar, --grad, .reveal (base) ni nada del nav/footer.
   - Los tokens propios de Lumina (--ink-*, --lav-*, etc.)
     son ALIAS de las variables de main.css.
   - Todo lo que podía chocar con main.css (.btn, button, img,
     section, h1-h3, :focus-visible) va acotado dentro de .wrap.
