Folder path with chevron separators. Current location renders in --text, intermediate links in --text-secondary. Over 5 segments collapse to … in the middle; click to expand. On mobile / sm breakpoint, only the parent's name remains as a back affordance.

Two-state sidebar. Active item gets --nav-item-bg-active + a yellow icon; metadata (storage size, badge count) right-aligns. Collapses to icons only.
