- Persist active puzzle state when joining/creating; restore on main menu load if incomplete
- Add Continue Puzzle button that only activates when a valid saved puzzle exists
- Implement Enter Fullscreen button with dynamic state handling and event listeners
- Adjust logo/sub-logo animation positions for cleaner visual flow
- Clear saved puzzle data on new puzzles or completion to avoid stale state
