/* ============================================================
   Solutions Dropdown — Redesigned for smooth UX
   Design principles (from ui-ux-pro-max):
   - Dimensional Layering: box-shadow elevation, top accent
   - Enterprise Gateway: promo panel fills right dead space
   - Smooth entry: @keyframes fade + slide (200ms ease-out)
