/**
 * Quests data-layer test (dev tool, run with Node — no browser):
 *
 *   node dev/quests.test.mjs
 *
 * Pins the contract behind the QUESTS console (the deck's QUESTS button
 * — right of SHIP, flight deck + surface deck → js/ui/QuestWindow.js):
 *   - quests.json is registered in data/manifest.json;
 *   - the window's knobs are present (title, the 2:3 video feed — the
 *     same dimensions as the research feed, sweep/glitch, the two
 *     category tabs with SIDE marked standby, the toasts);
 *   - the starter quest is well-formed: Main Story, one starter flag,
 *     a non-empty checklist of KNOWN requirement types, a reward that
 *     fits the ship's hold;
 *   - the 'research' check points at a REAL node of its category's tree
 *     (data/research/<category>.json — the check would never complete
 *     otherwise);
 *   - the quest ledger (js/quests/QuestState.js) behaves: idempotent
 *     give/claim, claimed ⊆ granted, a save round-trip, and a
 *     corrupted save degrades to an empty ledger (not a throw);
 *   - both command decks carry the QUESTS slot, right of SHIP.
