Problem
The sidebar always showed a horizontal scrollbar, even when content should fit.
Root Cause
The
.tree-itemclass in Sidebar.svelte hadwidth: 100%combined withmargin: 0 4px, making each item 100% + 8px wide, causing overflow.Fix
width: 100%towidth: calc(100% - 8px)to account for the horizontal margin.lines-wrapperfromdisplay: inline-blockwithmin-width: 100%to justdisplay: block(cleaner, no functional change since custom scroll only handles vertical scrolling)
