+/// Portable meeting export manifest — the `meeting.json` inside an export
+/// bundle folder (FR-STORE-4). Carries everything needed to reconstruct a
+/// meeting on another machine alongside the bundle's files (`audio.wav`,
+/// `transcript.json`, `notes.md`, `summary.json`). Deliberately excludes the
+/// meeting id (a fresh one is minted on import to avoid collisions) and the
+/// calendar-event link (event ids are machine-local).
