/* Account-backed bookmarks UI — warm carbon theme.
 *
 * Three surfaces styled here:
 *  1. Sidebar Bookmarks pane (folder tree, DnD, folder CRUD).
 *  2. Anon CTA card (replaces the empty state for non-logged-in visitors).
 *  3. Star button anon popover (re-parented to body, see bookmarks.js).
 *
 * All colors come from --bg-* / --text-* / --accent — no hard-coded grays.
