* Durable Object storage key schema.
*
* Each `RoomDO` holds one spreadsheet room plus its append-only logs. All
* keys live under the DO's own storage — key collisions across rooms are
* impossible because each DO has its own isolated storage (the legacy
* `snapshot-<room>` / `log-<room>` Redis namespacing is replaced by the DO
* namespacing itself, see CLAUDE.md §3.3 and §10.2).
*
* List-like data (log / audit / chat) is stored as individual keys with a
* zero-padded sequence number suffix so `storage.list({ prefix })` returns
* entries in insertion order.
