- MapLibre map is now a fixed, full-viewport background layer (z-0)
- New FloatingWindow: drag by title bar (pointer capture, viewport-clamped,
position persisted to localStorage), collapsible to title bar, bring-to-front
z-index; semi-transparent slate window with amber/cyan accents
- Game screen re-laid out as floating windows over the map: slim top header
(scenario, turn + date, player nation chip, Idle/Simulating status, Focus map
collapse-all), dossier (top-left), event feed (right), Your move deck
(bottom-center), legend (bottom-left), tiny zoom control (bottom-right)
- MapLibre default nav controls removed; custom floating zoom-in/out control
- Panels gain an inWindow mode (no card chrome, same testids)
- server: honor HISTORY_API_PORT as PORT fallback (dev proxy/e2e agreement)
- css: keep maplibre canvas base color and Radix portals above HUD windows
