 //!
-//! Input capture is a deliberate, reversible STATE (Moonlight-style, mirroring the other
-//! native clients): engaged when the user clicks into the window (that click is suppressed
-//! toward the host) or on first focus; released by Ctrl+Alt+Shift+Q (toggles) or focus loss —
-//! held keys/buttons are flushed host-side on release so nothing sticks down. While captured
-//! the cursor is hidden and confined; F11 toggles fullscreen.
-//!
-//! Keys are winit physical `KeyCode`s → VK via `keymap` (layout-independent). Mouse is
-//! absolute (`MouseMoveAbs` scaled into the negotiated mode through the letterbox transform,
-//! surface size packed in `flags`) — relative pointer-lock is a follow-up (RAWINPUT).
+//! Declarative React-like model: a single root component routes on a `Screen` value held in
+//! `use_async_state` so background threads (discovery, the session pump) can drive navigation.
+//! The present + decoded-frame handoff crosses to the UI thread through a `Mutex` side-channel
+//! and thread-locals (the windows-reactor SwapChainPanel sample's pattern), since the per-frame
+//! present must not go through state/rerender.

-//! sampling the video texture; a letterbox is produced by clearing the back buffer black and
-//! setting the viewport to the Contain-fit rect (no per-frame vertex buffer). This is the
-//! SDR 8-bit path; the 10-bit/HDR present (`R10G10B10A2` + `SetColorSpace1(...G2084_P2020)`)
-//! is a follow-up alongside the P010 D3D11VA decode.
