💡 What: Optimized the random number generation algorithm in `random.html` and improved UI handling for large result sets.

🎯 Why: The original implementation suffered from the 'Coupon Collector's Problem' when generating many unique numbers close to the total range, causing the browser to hang. Also, rendering large result sets without constraints caused layout thrashing.

📊 Impact:

  • Algorithmic speedup: ~41x faster for high-density requests (measured logic improved from ~1518ms to ~36ms for 999,990 numbers in 1M range).
  • UI: Prevents layout explosion by using a scrollable container for results.

🔬 Measurement: Verified with Playwright benchmarks comparing old vs. new logic execution times. Visual parity confirmed via screenshots.

- Implemented hybrid sampling strategy in random.html:
  - Uses rejection sampling (Set) for sparse requests.
  - Uses partial Fisher-Yates shuffle for dense requests (count > 50% of range).
- Resolved 'Coupon Collector's Problem' performance collapse, yielding ~41x speedup for high-density requests (e.g., 999,990 in 1,000,000 range).
- Improved UI responsiveness with CSS max-height and scrollable result container.
- Switched to textContent for faster DOM updates.
- Cached DOM references and fixed a bug in range validation.
- Initialized Bolt performance journal in .jules/bolt.md.
