/* ============================================================
   NAV MOBILE FIX
   Append to the BOTTOM of public/css/style.css

   THE BUG: .nav-links on mobile had padding: var(--space-md)
   in the closed state (max-height: 0). Padding is not clipped
   by max-height — so the browser rendered it as a white gap
   below the nav on every page.

   THE FIX: padding is 0 when closed, only added when .open.
   Everything else (colours, fonts, layout) is untouched.
