11 * A message part — a discriminated union on `type` (the global class discriminator).
12 * Unknown types decode to [UnknownPart] via the registered polymorphic default,
13 * so the stream survives server additions.
14 *
15 * Every part carries [id] plus its parent [messageID]/[sessionID], which the reducer
16 * uses to attach streamed parts to the right message.
