/* ============================================
   FAQ accordion — native <details>/<summary>-based collapsible
   Q&A. Single-card container holds the rows; each row has a
   question header and an expandable answer.

   Pair the visible accordion with a JSON-LD FAQ schema script in
   the same section for SEO (Google's FAQ rich result). Schema
   text should mirror the visible Q&A 1:1.
