The fix is scoped to the left rail: Home stays fixed at the top, Help/Settings stay fixed at the bottom, and the provider icons in the middle can scroll.

📝 Walkthrough

Walkthrough

SideNav adds a scrollable flex container around the draggable plugin icons area. The wrapper constrains height with min-h-0, enables vertical scrolling via overflow-y-auto, and applies scrollbar styling. Drag-and-drop rendering logic remains unchanged.
