/* ============================================================
   NAVBAR  (single source of truth — all navbar rules live here)

   The brand logo PNG (saki-icon-navbar.png) is ~700px tall at
   its native size. If the IMAGE is not clamped, it inflates the
   fixed-top navbar and the bar ends up overlapping the page
   content below it.

   Strategy:
   - Pin the logo image to a small fixed height (--lab-navbar-logo-h).
   - Let the bar size itself from that image + a little padding.
   - Do NOT set a hard navbar height + overflow:hidden, because
     that clips the expanded mobile (toggled) menu.
