/* ============================================================
   AskABD Shared Component Library — Phase 2 additions
   Breadcrumb, Accordion, Tabs. Reuses the existing design tokens
   from style.css (--navy-dark, --blue, --blue-bright, --text-gray,
   --text-light) and the existing scroll-reveal animation system in
   main.js rather than introducing a competing one.
