- New second main quest "Leaving the Nest" (data/quests.json) that unlocks when the starter quest's reward is claimed, with four checks: system charted, gates activated, Trestle talked, Trestle met
- Quest unlock chain in QuestState (isUnlockMet / grantUnlocked) and GameScene._grantUnlockedQuests — grants on claim + scene create for loaded saves, announces via SFX, OAC quest-grant voice (new oac-quest-new comm), and NEW QUEST toast
- Trestle story beats: three-brief ACK sequence (trestle-brief-1/2/3, trigger trestleBrief) armed when home jumpgates go online, and arrival beat (trestle-arrive, trigger trestleArrival) on landing in a neighbor system; CommsHub gains onStart hook so the played-ledger marks feed quest checks live
- Quest check types: systemCharted, gatesActivated, trestleTalked, trestleMet — evaluated in GameScene._questCheckEval / _trestleCheck against the comms played-ledger (survives reloads; mid-sequence quit re-arms only unplayed beats)
- System-complete milestone moved from research completion to the chart-completing discovery (celebrateDiscovery), one fire per system via _systemCompleteSeen set
- QuestTrackerHud READY state: completed-unclaimed rows turn amber with breathing tint, percent reads "READY" (bold), one-shot flash + diamond burst on flip, CLAIM REWARD button in row popup claims in place; silent when tracker is slid off (toast + chime carry it)
- New speech clips (trestle q2-01/02/03), lava-takeoff video, updated lava-land video, renamed lava-planet image, new laval-surface image
- Dev: quest-ready.html/mjs capture harness for the READY state shot; tests updated across comms, quests, quest-tracker, and system-hud suites
