/* ================================================================
   CEJM SHELL — SKIN « GLASS / BENTO »
   Variante visuelle additive (chargée APRÈS cejm-shell.css)
   Inspirée des pages de sommaire (cejm.html / adoc.html) :
   glassmorphism (flou, transparence, halos) + cartes façon bento.
   N'altère ni le HTML, ni le JS, ni les variables de thème —
   uniquement un re-skin visuel.
