/// What seals and opens a person's synced content, in pure Dart (Halkyon's

/// - **The envelope** every synced row is sealed in (`PayloadEnvelope`, on a
///   `ContentCipher`, ADR 0019): sealed for its table, row and what it belongs
///   to, readable rows signed; a file sealed alike (`SealedFile`, HLKF).
/// - **People's files** on the device and the module's store (`FileCache`,
///   `FileServerGateway`).
/// - **The account's keys**, unlocked (`UnlockedAccountKeys`), and new ones
///   for an account without a password (`newAccountKeys`, an agent's).
/// - **Shared spaces** (ADR 0044): their members and invitations through the

///   held to the public keys first seen (`SharedKeys`, `KeyPins`).
///
/// Rich text (`RichContent`, the editor's document JSON, which
