/* ══ BeFX Learning Hub (rediseño 2026-10) ═══════════════════════════════════
   Mismo lenguaje que BeFX Backstage (lineas finas, iconos de trazo fino de
   Lucide en linea desde hub/build.mjs, el color solo donde dice algo) con los
   colores de befxstudios.com: el azul marino del logo de BeFXWeb
   (src/brand-theme.css, data-theme="befx"), para que el Hub se vea como una
   seccion mas de la web. Cada add-on pone su color en --accent / --accent-2
   (page() en build.mjs); la portada usa el naranja de BeFX.
   Esqueleto de las paginas de un add-on: barra superior 52 px | panel 264 px |
   contenido (+ indice «En esta pagina» en pantallas anchas). En el movil el
   panel es un menu que se abre desde la barra (hub.js). */
