/* ==========================================================================
   FAQ (#faq) — light section
   Sheet-over-section top edge · sticky help column · WAI-ARIA accordion
   (height tween = grid-template-rows 0fr↔1fr, so it works without GSAP).
   Collapsed styles are scoped to .faq--js, which faq.js adds when it
   enhances the list — without it every answer stays visible.
