/* ============================================================
   ATLANTIS B&B — STYLES (refactored layout v6)
   - Nav is SEPARATE from header and main.
   - Nav top touches header bottom.
   - Nav right border touches main's left border (no overlap).
   - Nav "floats" down the page on scroll (handled in JS).
   - Nav never reaches the footer (clamped in JS + min-height here).
