-The first Android milestone uses the complete single-display fallback. Press
-Select (or Tab with a keyboard) to switch between the main game surface and the
-620 × 540 tactical surface. Native routing to both physical Thor displays is the
-next milestone; it needs two Android display contexts backed by one shared game
-state rather than two independent WebViews.
+The Android host routes the main and tactical surfaces to separate physical
+Thor displays while preserving one authoritative game state. If only one
+display is available, Select (or Tab with a keyboard) opens the tactical surface
+over the main game view.
+
+PC and handheld browsers use the Thor top screen as a responsive, full-viewport
+game surface. The compact ability strip keeps combat controls visible; Select
+or Tab opens party, map, inventory, and other tactical detail. Use
+`?layout=thor-preview` to restore the stacked dual-screen hardware mockup for
+browser QA.
