/* === SCHEMA.ORG FAQPAGE MARKUP HELPER ===
   RankMath auto-generates FAQPage schema from native <details>/<summary>
   or from RankMath FAQ block. Our CSS works with both.
   
   If using RankMath FAQ block, it outputs:
   <div class="rank-math-faq-item">
     <h3 class="rank-math-question">...</h3>
     <div class="rank-math-answer">...</div>
   </div>
