/* ══════════════════════════════════════════════════════════════
   FAQ Accordion — "most requested questions" chat-style accordion
   on the Home page, between #cta and the footer. Chat-bubble
   questions (plus/minus toggle, optional tilted emoji sticker) that
   expand into a gradient reply bubble, single-item-open at a time.
   Reuses .reveal / .section-label / .home-heading-friendly verbatim.
   Depends on tokens defined in scholars-ui.css (:root vars) — most
   colors below inherit theme automatically via var(--surface) etc.;
   only the accent tints need explicit dark overrides.
