The only writer of draft-msg-<key> is the effect cleanup, which React runs on unmount / draftKey change. There is no pagehide/beforeunload/debounced save anywhere in the app (grep for beforeunload returns nothing). So a draft typed in the currently-open room and never navigated away from is lost on refresh, tab close, or crash — even though useHydrateMsgDrafts exists specifically to rehydrate drafts "after a reload". The composer's own DraftIndicator also stays hidden for the open room for the same reason (the atom is only written on leave), so the "Draft saved" affordance never appears while you are actually typing.
How to trigger
Type a message in a room, press F5 without switching rooms — the draft is gone.
Suggested fix
Add a debounced (or pagehide/visibilitychange-triggered) write of editor.children to the atom + localStorage while typing, reusing the existing cleanup serialization.

### Problem
The only writer of `draft-msg-<key>` is the effect **cleanup**, which React runs on unmount / `draftKey` change. There is no `pagehide`/`beforeunload`/debounced save anywhere in the app (grep for `beforeunload` returns nothing). So a draft typed in the currently-open room and never navigated away from is lost on refresh, tab close, or crash — even though `useHydrateMsgDrafts` exists specifically to rehydrate drafts "after a reload". The composer's own `DraftIndicator` also stays hidden for the open room for the same reason (the atom is only written on leave), so the "Draft saved" affordance never appears while you are actually typing.
