🎨 Palette: CLI Game UX Enhancements

- Colorized countdown digits (Yellow) and 'GO!' prompt (Green).
- Added real-time high-score tracking in the gameplay HUD.
- Enabled 'NEW BEST!' achievement and congratulations for first-time players.
- Ensured terminal cursor is hidden/shown correctly and HUD clears properly.

 ## 2026-03-02 - Hiding the Cursor in CLI Games
 **Learning:** In terminal applications that require rapid visual updates or where user input doesn't involve typing text, an actively blinking cursor can be a visual distraction. Hiding it during interaction (`\033[?25l`) and rigorously ensuring it is restored (`\033[?25h`) on exit—including signal interrupts—significantly improves the aesthetic and focus.
 **Action:** Always hide the cursor for interactive CLI games and explicitly restore it across all exit paths, including async-signal-safe signal handlers.

+## 2025-01-24 - Real-time Achievement Feedback in CLI
+**Learning:** In terminal-based games, displaying achievement progress (like a live high score) in real-time provides immediate tactile reward and engagement. Furthermore, inclusive UX means ensuring first-time players also receive "New Best" feedback, even when their initial record is zero.
+**Action:** Update session-high-score variables immediately upon record-breaking and display them in the live HUD. Ensure achievement conditions (`score > highscore`) don't exclude the first-time user experience.
