 **Learning:** For CLI-based onboarding, providing immediate feedback on execution duration via `time.perf_counter()` and using titled `rich.Rule` components significantly improves the professional feel and clarity of the workflow completion state.
 **Action:** Incorporate high-resolution execution timing in final result panels and add descriptive titles to terminal rules to better guide users through multi-step onboarding processes.
 
+## 2026-04-03 - [Consistent CLI Aesthetics & Data Integrity]
+**Learning:** Using `box.ROUNDED` for `rich.table.Table` components ensures visual consistency with rounded `Panel` elements, creating a more polished and cohesive CLI experience. Furthermore, using `random.sample` instead of `random.choices` for demo data prevents confusing duplicates, which improves the perceived reliability of the workflow being demonstrated.
+**Action:** Apply consistent border styling across all container components and prefer unique data generation for tutorial-style outputs to maintain a high-quality user experience.
 ## 2026-04-02 - [Micro-UX Polish for Demo CLI Scripts]
 **Learning:** For tutorial-style CLI scaffolds, several micro-UX touches significantly improve the professional feel and onboarding experience: (1) using `random.sample` instead of `random.choices` for unique mock data generation; (2) displaying the total execution duration in the final success panel; and (3) adding descriptive titles to `rich.Rule` components for better visual hierarchy between results and "Next Step" guidance.
 **Action:** Ensure all demo scripts use unique mock data, provide performance feedback via execution duration, and utilize rule-titles for clear sectional separation.
