/* ============================================================================
   Velo Working — shared site navigation (single source of truth).

   This file styles the navigation bar that appears on EVERY page
   (home, Fabrication, AI quote, Field notes / blog, Assessment).
   The markup is injected by /nav.js, so to change the menu you only edit
   nav.js (links/labels) and this file (styling) — once — and every page
   updates automatically. No more keeping pages in sync by hand.

   Self-contained on purpose: colours and font are hard-coded here so the bar
   looks identical regardless of the host page's own CSS variables.
   ============================================================================ */

/* Reserve the bar's height (and match its look) before nav.js runs so the
   page never jumps and there is no blank flash. */
