/*
 * Shared collection-control styles for the tracker (/tracker/) and demo (/demo/)
 * pages. Both include tracker/_collection_controls.html, so the chrome around
 * the search box, filters and type chips lives here instead of being duplicated
 * in each template's inline <style>.
 *
 * The card is pinned to the bottom of the viewport at every width; only its
 * shape changes (grid areas do the reordering):
 *   desktop (>720px) - a full-bleed bar: name + count pill on the left,
 *                      search / filter / types / theme on the right, all of it
 *                      always visible.
 *   mobile  (<=720px) - a slim dock (count pill + hamburger) that mirrors the
 *                      fixed top nav, with the filter sheet sliding up over a
 *                      dimmed page.
 *
 * Colour comes from the per-page custom properties (--text, --accent, ...),
 * so this file works unchanged on both light and dark themes.
