/* ═══════════════════════════════════════════════════════════════════════════
   nav.css — the control bar, the menu, the footer.
   The bar floats over every page like a piece of studio equipment: a white
   pill, blurred glass, the wordmark on the left, the black Book pill on the
   right. Under 900px the links move into a full-screen menu.
