//! Server-Sent Events (SSE) streaming infrastructure.
//!
//! The SSE implementation uses a typed internal stream model:
//! - producers emit `StreamFrame` values (control, notifications, heartbeat, errors, close)
//! - helpers apply lifecycle rules (shutdown/timeout/end-of-stream)
//! - a single renderer converts frames to wire-format SSE bytes
//!
//! This keeps endpoint behavior stable while making stream lifecycle easier to reason about.

// Re-export the small public surface that is genuinely consumable outside
// this module (formatting helpers and the response builder). The stream
// constructors and the byte/event renderers are crate-private because
// their signatures embed aviso-internal types (NotificationMessage,
// CancellationToken, the request_id correlation contract, NotificationBackend
// trait objects); they are never called from outside `src/`.
