Catan Compose UI: board, placement flow, personal panel, event feed
- CatanScreen.kt: Canvas hex board using CatanBoard geometry (hexCenter, VERTEX_POS, EDGE_VERTICES)
- Tap-to-target + commit pattern with detectTapGestures (Ta Yü precedent)
- BoardGeometry for vertex/edge hit detection
- drawTerrains, drawBuildings, drawRoads, drawNumbers, drawPorts, drawRobber, drawDice
- Legal-target highlighting for settlement/road/city/SetupPlace
- Personal panel: resources, dev cards, VP, longest-road/largest-army banners
- Commit/End-turn/Roll buttons with 48dp targets
- CatanEventFeed: shows last 4 log entries (seat-redacted via CatanRules.viewFor)
- Layout: Column with Modifier.weight(1.6f) board region — rotation-safe, measures space
- PlayScreen.kt: CATAN case wired with CatanRules + CatanAi
- GameCatalog: CATAN entry (available=false, menus=Board) — dev builds show it
