/* --- Dropdown nav ---
   RULE: Never use margin-top or top: calc(100% + Npx) on absolute dropdowns.
   Any gap between the trigger and the dropdown will cause hover to break mid-travel.
   Instead, set top: 100% and use border-top: Npx solid transparent on the dropdown
   so the element extends upward invisibly, keeping :hover alive across the gap.
   The mobile override (position: static) is exempt — no gap issue there.
