/* Shared header nav - used by every plain-HTML page (tos, privacy, docs,
   permissions, report, upgrade, u/:username) so the header never drifts
   between pages again. The React dashboard (Home/Dashboard/Admin) uses its
   own Nav.jsx component, styled from dashboard-src/src/styles.css - these
   rules are a deliberate 1:1 copy of that component's CSS so both look
   identical, not a shared stylesheet, since the two apps build separately. */
