/* ============================================================
   AURA AVENUE — sidebar.css
   Persistent left navigation in the Jacob & Co register: large
   restrained serif, generous vertical rhythm, hairline rules,
   bronze on near-black. Collapses to the overlay menu under
   1080px so mobile keeps the burger.
