/* D4: Global navbar auto-hide (all pages) — VISUAL only.
   Do NOT set pointer-events:none on the hidden nav. The only element in the
   nav's 48px viewport footprint is the non-interactive .nb-spacer (which
   merely reserves space below the fixed nav), so an always-hit-testable nav
   blocks nothing usable. Disabling pointer-events (an earlier D4 revision)
   made #nb-logout-btn unclickable when the nav was idle-hidden: the click
   passed THROUGH the transparent nav and landed on the spacer below —
   empirically confirmed by Playwright ("nb-spacer intercepts pointer events
   over nb-logout-btn"). Keeping pointer-events at its default (auto) means
   the logout button is always clickable; the nav just fades visually. */
