1//! Bridge that forwards global hotkey / input events into the renderer's
2//! outbox, so the frontend receives them as unnamed `window.__RDESKTOP_PUSH__`
3//! messages (matching the IPC contract used by the Node extension host).
4//!
5//! `PushHandler` implements both [`HotkeyHandler`](crate::hotkeys::HotkeyHandler)
6//! and [`GlobalInputHandler`](crate::input::GlobalInputHandler) and writes a
7//! JSON envelope into a shared `outbox` queue drained every frame by the
8//! backend event loop.
