/* =========================================================================
   WA.Expert design system v2  (session 1, October 2026)
   Lives alongside css/style.css, which is left untouched.
   Keeps the existing class names used by js/main.js (nav, dropdowns,
   mobile nav, FAQ, scroll-reveal, counters) so pages can move over one
   template at a time.
   Light theme only until every page is on v2.
