All editors now work on a server document at the same time instead of
taking turns behind an edit lock.
- The document's content is a sequence of Yjs updates (document_updates);
DocumentChannel stores and relays them immediately, checks access on
subscribe and again whenever links or memberships change.
- app/frontend/collab/: the store stays position-based; a binding maps it
to a Yjs form with stable row/column ids, so a row inserted by one
person doesn't misplace what another is typing. Remote changes are
applied only after pending local ones went into Yjs.
- Per-person undo (Y.UndoManager), presence via awareness: the others'
selections as coloured boxes with names, avatars in the toolbar.
- Existing JSON documents convert on first open, deterministically, so
two people opening one at once end up with the same Yjs state.
- Editors compact the stored updates after 200 and keep a JSON snapshot
current for export and duplicating. Edit lock and polling are gone.

The app becomes a Rails 8 application; the Vue frontend moves to
app/frontend and is served through vite_rails.
- Without an account documents stay in the browser (IndexedDB). Sign-in
is by magic link or the 6-digit code from the same mail; afterwards
local documents can be uploaded into the account.
- Server documents (/d/<id>) with versioned saves and a single-editor
lock per browser tab; others see them read-only and follow by polling.
- Sharing via link (works without an account) and via e-mail invitation,
roles viewer/editor; the owner manages links and people.
- Store gains a read-only mode that blocks all content changes.
- Solid Queue, Cache and Cable share the one PostgreSQL database.
