/* Top Navigation Enhancements - Scroll reveal & banner overlay
   --------------------------------------------------------------
   Behavior:
   - Header starts hidden (translated upward) and overlays the banner with a gradient.
   - Once user scrolls a bit (>10px), header slides in (header--visible).
   - While within the banner height, header uses overlay style (transparent gradient, light text).
   - After passing banner height, header becomes solid (white background + shadow) and spacer div creates layout offset.
