The Shop button on the deck is now always live — the shop sub-bar opens on every world. The "Special Delivery" capital-landing witness now gates only the shop's Buy/Sell tab (ShopView reads GameScene.isTradeUnlocked, which replaces isShopUnlocked), so trading stays dark until the player lands on the neutral capital while the rest of the shop UI is reachable everywhere.
- Rename GameScene.isShopUnlocked → isTradeUnlocked and update all references (SaveData, SurfaceScene, quests.json comments)
- Remove the deck-slot enable guard in SurfaceScene.toggleShop / setBarLocked; the slot now re-arms with the rest of the deck
- Add ShopView.isTradeUnlocked + gate checks in setTab / _onTabTap; gray the Buy/Sell tab via _refreshTabs until the gate lifts
- Update dev probes (scout-*, shop-*) to lift gs.story.capitalLanded so the trade panel is reachable
- Extend shop-ui.test.mjs with a TRADE GATE case covering closed/lifted states
