/* ===== Toggle de tema =====

   - role="switch" + aria-checked: solo brand/showcase.html.
   - <button> con aria-pressed (rol de botón implícito): TODO lo demás — el chrome
     de marketing (apex/docs/developer/reference, vía site.js) y el panel
     (frontend/app/ui/ThemeToggle.tsx). Es el patrón real de producto.
   Antes esta 2ª variante solo vivía duplicada en marketing/assets/site.css (cargado
   únicamente por apex/ayuda/status) — docs/developer/reference quedaban con el
   botón "switch" pero SIEMPRE en estado visual apagado, sin importar el tema activo
   (Ola4 T7: matriz de consistencia). Se centraliza aquí, la única hoja que cargan
   las 4 superficies, para que el estado visual sea idéntico en todas. */
