Every document-scoped key now goes through docKey(), which hangs it off the tab's document id; the first document keeps the empty id, so existing browser copies read back unchanged. A fresh tab takes up the most recently used document no live tab holds, else starts a new one — one signed timestamp per document (edentext-live@id) says which, written only by the tab holding it. Snapshots and embedded fonts get a database per document. The picture store stays shared and content-addressed, so its sweep now drops only keys no stored document names any more, instead of the open document's own.
