   TRESUN-TECH — FAQ page stylesheet (Layer 2)
   File: assets/css/faq-page.css
   Scope: every selector is prefixed with .tsq-faq — no global element, no
          theme class and no other page of the site is affected.
   Companion: layer1-content.html (structure) · layer3 FAQ JavaScript (behaviour)
   Suggested pairing: enqueue on the FAQ route only, version = filemtime().
