📝 Walkthrough

Walkthrough

The inline pagination logic was moved from main.js into the exported paginate helper. The helper collects query results, navigates between Hacker News pages, and stops after the requested page count. A test verifies three-page collection and the two expected navigation calls.

Priority: ⬇️ Low

Merge Risk: ⚪ Minimal · up to b3b06

The pagination change avoids the unnecessary final navigation and includes coverage for the intended boundary. No actionable merge risk remains.
