/* NurdHub — the 3D experience shell, ported from intelligysoftware.com.
 *
 * Two layouts share one document:
 *   - default (no JS, no module support, no WebGL, or html.no-webgl): the beats
 *     flow top to bottom as a normal page, and the stage layers are hidden;
 *   - html.xp (set by the head script and confirmed by initShell): a fixed
 *     canvas stage with the beats layered over it, driven by scroll.
 * Every fixed-stage rule is scoped under html.xp so the fallback never needs
 * its own overrides. Single dark world by design: one machine in a dark room.
