/* ============================================================
   MEA Reviews — FAQ Accordion
   Frequently-asked-questions block for review pages. Built on
   native <details>/<summary> so it works with zero JavaScript
   and stays keyboard-accessible. Carries schema.org FAQPage
   microdata for rich results. Light "tech / computer" theme,
   matching top3-cards / category-cards / footer. Tokens are
   scoped to .mea-faq so they won't clash with page :root vars.
   Needs only this stylesheet — no external CSS or JS.
