/* ── Scroll-fix overrides ─────────────────────────────────────
   These rules override earlier declarations that caused the page
   to lose scroll when the Problem Statements dropdown was open.
   • .hero overflow changed to visible so the absolutely-positioned
     dropdown is not clipped by the hero section.
   • .ps-dropdown gets overflow-y:auto + max-height so it can scroll
     internally without ever locking the page scroll.
   • z-index raised to 9999 so it always renders on top.
   No JS changes are needed — the existing close-on-outside-click
   script never touches document.body.style.overflow.
