 * (position:fixed, see panels.css) — there is no separate header
 * strip/band behind them. Gilles, 2026-09-25, rejecting an earlier version
 * that grouped them into a bordered header: "tout au meme niveau, un seul
 * conteneur commun." Matches ostnoctua's own #on-layer + .on-modbar +
 * .on-conn-cluster, all floating "glass" chips over one canvas (see
 * ostnoctua/web/ostnoctua.css and panels.css's .glass) — panels.js's
 * header explains the one real behavioral difference (drag/resize math
 * relative to the canvas, not the window). */
