## Major features
- [~] **Rollback of game state.** *Phase 1 implemented* (full-state JSON snapshots in a `Checkpoint` table, captured per action by the broadcast middleware, restored by `crud_rollback.rollback_to_checkpoint`; scene-confined; server-enforced for Admins and Deep players; event-log buttons in `EventLog.svelte`). **Phase 1 truncates the future immediately (no undo).** *Phase 2 (remaining):* the greyed-out / undoable redo UX — roll back without discarding the future, grey later entries, and only commit the truncation when a new action is posted. The schema is already forward-compatible for this (add `Game.rollback_head_checkpoint_id`).

## Words Words Words

- [ ] **Example Play formatting.** The Example Play section of the Rules page could use a bit more formatting for legibility. Make diagrams of the card state at each step rather than just a text listing. 
- [ ] **Suggestions.** Take a pass through all of the suggestions in suggestions.js, rewrite ones that are stiff, awkward, or don't fit the theme/setting as described in the rulebook. Move the suggestion pool from suggestions.js into a backend API endpoint.
- [ ] **TLDR rules**. A one page summary sheet of the rulebook, for the impatient

## Security

- [ ] **Defensive coding.** While we trust our players, this app is exposed on the open internet. I'd like to take basic precautions like making sure we're safe against SQL injection (SQLModel should handle this?), doing some basic sanitizing of free inputs from players (valid unicode only + generous character limit should be enough), and making sure that every game action API call is specific and constrained enough that it can't just do arbitrary database updates.
