/* ============================================================
   PeppolBridge — FAQ accordion (site-wide upgrade)
   Load AFTER style.css / light.css / scene3d.css.
   Pairs with assets/faq.js (loaded after main.js).

   Specificity notes (deliberate — no !important needed):
   - style.css legacy rules are .faq-item / .faq-q / .faq-x /
     .faq-a p at (0,1,0)–(0,3,0). Everything here is prefixed
     with .faq-wrap to sit one class above them.
   - scene3d.css sets frosted glass via `html.has-bg3d .faq-item`
     at (0,2,1). The base card below stays at (0,2,0) so the
     frost keeps winning; only the .open tint goes to (0,3,1)
     via the `html` prefix to override it intentionally.
