- New QuestTrackerHud component slides in below the system dossier once it folds, showing active quests (main story first) with a live progress checklist under the priority quest
- Priority quest: player can set/clear via row popup or console; auto-assigns to first active story quest; cleared state sticks until a grant or claim re-arms it
- QuestWindow gains SET PRIORITY / CLEAR PRIORITY controls and openAt() to land on a specific quest (used by SHOW MORE / VIEW QUEST)
- GameScene wires the tracker into the dossier lifecycle: hidden while expanded, slides out before expand, slides in on collapse; pointerdown contract prevents world clicks from leaking through rows and popups
- SurfaceScene delegates priority changes to the sleeping GameScene's ledger
- QuestState serializes/deserializes priority + cleared flag for save round-trips
- quests.json gains a tracker section (title, maxVisible, slideMs, toast configs)
- New dev/quest-tracker.test.mjs pins the full contract; dev/quests.test.mjs extended with priority and tracker-knob checks; system-hud test updated for the extra tracker elements
