MapInteraction bound DOM events to the WebGL canvas, but the canvas has
pointer-events: none post-migration so its pointermove/down/up/wheel/
keydown listeners never fired — duplicating InputHandler (which owns
the inputOverlay div + EventBus pipeline) and leaving most features
dead. The one alive bit was hover→setHighlightOwner, which I'd
manually forwarded as a workaround.
Now there's a HoverHighlightController that listens to MouseMoveEvent,
computes the cursor's tile owner, and pushes setHighlightOwner. Delete
map-interaction.ts (418 lines) + keyboard-pan.ts, trim the DOM-binding
constructor + proxy methods (setFitZoomOnDoubleClick, setPanSpeed,
setZoomSpeed, etc.) out of GameView, and drop the ClientGameRunner
pointermove forwarder.
Input flows through one path: DOM → inputOverlay → InputHandler →
EventBus → controllers/renderer.
