/* =====================================================================
   navbar.css — self-contained navbar styling for the baked partials.

   Extracted from the reference system's bh/globals.tsx nav block
   (salon-generator-fresh) and dedented into a standalone stylesheet.
   Pair this with one HTML partial from this folder (see manifest.json).

   ── DESIGN-TOKEN CONTRACT ─────────────────────────────────────────────
   The generated page MUST define these CSS variables in :root, otherwise
   the navbar falls back to the values below:

     --bg          page background (light)         e.g. #faf8f5
     --text        primary text                    e.g. #1a1815
     --text-muted  muted text (icon nav links)     e.g. #6b6660
     --accent      brand accent                    e.g. #b08d57
     --border      hairline border color           e.g. #e3ddd4
     --font-display  display / heading font (brand) e.g. "Cormorant Garamond", serif
     --font-body     latin body font (nav labels)   e.g. "Jost", sans-serif
     --font-jp       Japanese font                  e.g. "Zen Kaku Gothic New", sans-serif

   ── BODY CLASS CONTRACT (only matters for the two *-cinema variants) ──
   - Home/hero pages with a dark image hero:  <body>            (nav starts transparent over hero)
   - Subpages WITHOUT a dark image header:    <body class="is-subpage">
   - Subpages WITH a dark image header:        <body class="is-subpage has-dark-image-header">

   ── LAYOUT NOTE ──────────────────────────────────────────────────────
   The nav is position:fixed. Give the page's first section enough top
   padding (or the <body>) so content isn't hidden under the bar (~72-88px).
