/**
* `<lr-realtime-session>` — a provider-neutral voice-session shell composing connection status,
* live activity, transcript, native capture, mute, interruption, and connect/disconnect intents.
* Transport, authentication, audio playback, and SDK ownership remain with the host.
* State transitions transfer focus from a disappearing session action to the replacement
* connect/disconnect action. Hiding the public capture surface does the same only when capture
* owned focus; surviving or foreign focus is never moved.
*
* Public collection properties take bounded, clone-owned readonly snapshots. Create a new
* collection and reassign it after changes; mutating the assigned array does not update the view.
*
* @customElement lr-realtime-session
* @slot controls - Additional provider-specific controls.
* @event lr-connect - Connection was requested.
* @event lr-disconnect - Disconnection was requested.
* @event lr-mute-change - A controlled microphone mute change was requested.
* @event lr-interrupt - Interruption of the current response was requested.
* @event lr-record-start - Passthrough from capture. `detail: { stream: MediaStream }`.
* @event lr-record-chunk - Passthrough from capture. `detail: { blob: Blob }`.
* @event lr-record-stop - Passthrough from capture. `detail: { blob: Blob; durationMs: number }`.
* @event lr-record-cancel - Passthrough from capture with no detail.
* @event lr-record-error - Passthrough from capture. `detail: { error: DOMException | Error }`.
* @event lr-level - Passthrough from capture. `detail: { level: number }`.
* @event lr-record-state-change - Passthrough from capture. `detail: { state: PushToTalkState }`.
* @csspart base - The named session region.
* @csspart header - Status and session controls.
* @csspart status - Connection status badge.
* @csspart activity - Voice activity visualization.
* @csspart controls - Built-in and slotted controls.
* @csspart connect - Connect action.
* @csspart disconnect - Disconnect action.
* @csspart mute - Controlled mute action.
