- Replace the surface deck's SHIP slot with an EXPLORE drawer that folds up a full-width secondary bar (MenuSubBar span mode) carrying per-world service items resolved by a `where` clause matcher (world / planetClass / faction, case-insensitive, list any-match)
- Add the neutral capital's BAR clip toggle: swaps the surface loop for the world's bar video, relabels the slot to LEAVE BAR, and locks every other deck + drawer button until pressed back
- Record quest checklist steps as DONE on the ledger (QuestState.completed set) so a step that stands on the home world keeps standing after the ship leaves; save/load round-trips the witness and old saves degrade cleanly
- QuestWindow fresh open now lands on the run's priority quest (tracker HUD seam) with its tab activated, falling back to the active tab's first quest when no priority is set
- MenuButton.setLabel re-fits the panel and hit rect in place for the LEAVE BAR relabel; ExploreBar.js provides the pure worldContext / matchesWhere / resolveItems item logic
- Add dev tests: explore.test.mjs (deck, items, where-clause, span, relabel) and quest-window.test.mjs (open landing + priority), plus updates to quests/research-builds tests for the new surface deck layout
