//! WebSocket subsystem: the browser bidirectional path
//! (ADR-067, `docs/architecture/decisions`).
//!
//! A WS session carries the **channels protocol**: the 8-byte chunk
//! header multiplexes N logical channels over the WS binary message
//! stream; channel 0 is pre-negotiated as `alk/call` and dispatched by
//! the shared `Dispatcher`. The WS↔byte-stream adapter (`byte_adapter`)
//! is the single seam between axum's WS and
//! alkcall's byte-oriented channels machinery — shared with the
//! `from_wss` consumer path ([ADR-070]).
//!
//! Feature sides: `upgrade` (and the axum flavor of the adapter)
//! compile under `server`; the tungstenite flavor compiles under `wss`
//! (and under `test-support`); both are available with both features.
