/**
 * The mineral HOLD across game entry points — the upper-right readout
 * (js/ui/MineralHud.js) must show the player's current inventory in all
 * three cases the player can enter the game:
 *
 *   1. NEW GAME — the hold is empty; the HUD reads 0 / capacity.
 *   2. MINE — minerals come aboard; the live seam (mining's onOre →
 *      GameScene.refreshMineralHud) pushes them to the readout.
 *   3. CONTINUE / LOAD — the save carries the hold (captureState),
 *      prepareLoad stages it (the exact seam both menu buttons use),
 *      and the fresh GameScene's applyRestore must land it BOTH on the
 *      ship AND the upper-right HUD. (The regression this guards: the
 *      HUD was seeded with the fresh ship's 0 in create() and never
 *      followed the restored value — the corner read 0 until the next
 *      mining run.)
 *
 * Two-scene harness: the real entry flow SWITCHES scenes (game → menu →
 * game) — and this Phaser build's scene.start is a no-op on the scene
 * that is already active — so a bare DummyMenu scene stands in for the
 * real MenuScene. The data seams are driven directly:
 * captureState → prepareLoad → scene.start('DummyMenu') →
 * scene.start('GameScene') → consumeRestore → applyRestore.
 * (The full UI version of this flow lives in dev/saves-ui-test.mjs.)
 *
 * Served by dev/hold-restore.html; results land in
 * `window.__HOLD_RESTORE__` for the CDP runner:
 *
 *   python3 -m http.server 8080
 *   node dev/cdp-firefox.mjs http://localhost:8080/dev/hold-restore.html \
 *     'return window.__HOLD_RESTORE__;'
