 ## 2024-04-24 - Avoiding Trailing Artifacts in CLI Applications
 **Learning:** When dynamically updating terminal lines using carriage return (`\r`), relying on hardcoded padding spaces to overwrite old text is brittle and leads to trailing text artifacts when new lines are shorter than previous ones.
 **Action:** Always use the ANSI escape sequence `\033[K` (Erase in Line) immediately after the carriage return (`\r`) to cleanly clear the line before writing new content, rather than manually managing padding spaces.
+## 2024-08-25 - Provide explicit empty states for data
+**Learning:** Hiding UI elements when data is empty (like a high score of 0) makes the system state less clear and misses an opportunity for user onboarding and encouragement.
+**Action:** Provide explicit, encouraging empty states (e.g., "None yet! Play to set one!") instead of just hiding the element.
