📝 Walkthrough

Walkthrough

The useOutsideClickDetector hook is removed entirely from the codebase. The sidebar component no longer uses this hook, eliminating the outside-click detection behavior. The sidebar retains only its window-resize-based toggle functionality.

Changes

Cohort / File(s)	Summary
Hook Removal packages/hooks/src/use-outside-click-detector.tsx	Complete deletion of the useOutsideClickDetector hook export and its entire implementation, including the mousedown event listener logic and useEffect lifecycle.
Sidebar Component Update apps/web/core/components/sidebar/sidebar-wrapper.tsx	Removed import and usage of the deleted useOutsideClickDetector hook; outside-click-to-close sidebar behavior eliminated while window-size toggle behavior retained.

Poem

🐰 The hook is gone, no more clicks around,
Sidebar closes only when screens shrink down,
Simpler it is, no tangled affairs,
One less behavior floating in there! ✨
