   fixed always stays put regardless). Blends fully into the page at the
   very top (no border/shadow); once the page scrolls even a little it
   solidifies into a distinct floating bar — same pattern as the main
   site's .dl-nav / .dl-nav-scrolled. Colors use the real theme variables
   (--brand/--txt/--surface/--border/--page-bg), so dark mode and every
   accent theme (violet/cyber/sunshine/aurora) are handled automatically —
   no separate per-theme override blocks needed. ── */
