/**
 * A sidebar that nests itself.
 *
 * Hand it the flat list of routes an app already has — with a category on each
 * — and it groups, orders, and renders them as a tree: the branches above the
 * current page open on their own, the row for that page is marked and scrolled
 * to, and which branches are open survives a reload. Rows are real links on
 * web, so cmd-click, middle-click and crawlers work.
 *
 * Everything past `items` has a default that suits a docs sidebar, so the
 * one-prop version is the intended way to use it:
 *
 * ```tsx
 * <NavTree items={ROUTES} activeHref={pathname} onNavigate={i => router.push(i.href)} />
 * ```
