/**
 * Append-only record of action bytes per frame. Useful for offline replay,
 * bug reproduction, and demos.
 *
 * Each entry stores a copy of the action bytes for one frame. The bytes
 * typically come from the per-frame `ActionLog` buffer (the action portion
 * after `Replicator.pack_for_peer` strips prior-state). The format on the wire
 * is the same one `Replicator.unpack_from_peer` consumes, so a recorded
 * session can be replayed by feeding the bytes back through a peer.
 *
 * Persistence to disk / IndexedDB / network is left to the application —
 * `serialize_to_buffer` produces a single contiguous `BinaryBuffer` snapshot.
