Module pointer_icon_session 

The pointer icon the platform should be drawing right now.

The shell resolves the hovered region’s PointerIcon on every pointer move and records it here; the platform layer reads the pending change back and applies it to the window it owns (winit’s Window::set_cursor on desktop, the canvas’s CSS cursor on the web). The indirection exists because neither side can call the other directly: cranpose-ui cannot reach a window handle, and the platform backend is not on the stack when a modifier declares its icon.

Reading is a poll rather than a callback because a windowing system wants the cursor set from its own event loop, holding the handles only that loop has: the platform asks for the change at the point where it can act on it.

The session is stored per AppContext, like the clipboard and text-input sessions, so each window in a multi-window app carries its own pointer icon.
