/**
 * Z-order + input-state probe (headless browser — NOT a Node test).
 *
 * Verifies the two menu fixes against the real engine:
 *
 *   Z-ORDER (paint order — the scene display list is depth-sorted
 *   ascending, and containers expand their children inline at their
 *   slot, so list order IS back-to-front paint order):
 *     stars(0-2) < planet(5) < ship(10) < HUD(30) < compass(40)
 *               < toast(45) < command deck(50) < menu sub-bar(60)
 *               < save pop-up(70)
 *   ... and the confirm dialog is the pop-up's last content child (only
 *   the toast trails it, and it sits outside the dialog's area), so it
 *   paints on top of the pop-up.
 *
 *   INPUT STATE (v4 gates hit-testing on `input.enabled`):
 *     sub-bar buttons inert while closed, live while open
 *     pop-up scrim / cards / footer inert while hidden, live while shown
 *     confirm scrim + buttons inert while the dialog is hidden, live
 *     while it is up
 *
 * Served by dev/zorder-test.html; results land in `window.__ZORDER__`:
 *
 *   python3 -m http.server 8091
 *   node dev/cdp-firefox.mjs http://127.0.0.1:8091/dev/zorder-test.html
