   FAQs page (page-faqs.php) — editorial two-column accordion
   Reuses the .accordion / .accordion-item base from atelier.css
   and the brand tokens (--ink, --stone, --line, --paper-tint…).

   Hierarchy:

     · Question       → right column, sentence case, medium
     · Answer         → quiet body copy
