   FAQ Knowledge Hub — searchable accordion
   Used by: /youve-asked-we-answered.php and /sl/youve-asked-we-answered.php
   Brand: "The Clear Signal" — white/navy field, azure as the one signal.
   Progressive enhancement: without JS every answer is visible (crawler-safe);
   the .faq-enhanced hook (added by faq-hub.js) turns rows into an accordion.
