   REVEAL / TOAST
   ────────────────────────────────────
   [FIX 2026-07-29] Blindaje ante fallos de JS.

   ANTES (regla original, se deja comentada para poder
   revertir si hace falta):

     .rv{opacity:0;transform:translateY(18px);transition:opacity .6s var(--ease),transform .6s var(--ease)}
     .rv.on{opacity:1;transform:none}

   PROBLEMA que causó: .rv pone opacity:0 incondicionalmente
   en el CSS. Que ese opacity vuelva a 1 depende por completo
   de que initReveal() (en dojo.js) se ejecute y añada la
   clase .on. Si CUALQUIER script anterior en la página lanza
   una excepción (p. ej. una llamada a una función que ya no
   existe, como pasó con guardPlayer() en frontend.html),
   initReveal() nunca se llama y el contenido queda invisible
   para siempre — sin ningún error visible en pantalla, solo
   en la consola del navegador. El HTML es perfectamente
   correcto; el fallo es una dependencia silenciosa del CSS
   respecto al JS.

   SOLUCIÓN: la clase document.documentElement.classList
   .add('js') ya se añade al principio del <body> de cada
   página (ver <script>document.documentElement.classList
   .add('js')</script> justo tras <body>). Se usa ese hook
   para que el estado oculto (opacity:0) SOLO se active si
   el navegador ha empezado a ejecutar JS con normalidad.
   Sigue sin ser una garantía absoluta (un script roto ANTES
   de initReveal seguiría dejando .on sin aplicar), pero
   elimina el escenario más habitual y además deja constancia
   clara en el propio CSS de que esta animación es opcional,
   no estructural: si algo falla, lo peor que pasa ahora es
   que el contenido aparece sin la animación de scroll, nunca
   que desaparece.

   Ver también en dojo.js: el failsafe por timeout dentro de
   initReveal(), que fuerza .on a los 1.5s como segunda red
   de seguridad independiente de este hook .js.
