Restore writes a safety checkpoint first, then swaps the document outside undo/redo. Media assets referenced by any version are pinned against deletion. Migration v31-v32 stamps the schema; the version store lives in its own IDB database with an in-memory fallback for tests. Versions popover in the editor header for jump/rename/delete. 12 new tests.
