   PATH: /css/faq.css
   TYPE: stylesheet
   STATUS: shared
   USES: reusable FAQ accordions across homepage, FAQ page, support pages,
         and canonical city-page FAQ sections

   PURPOSE
   This file owns the FAQ component system used for:
   - homepage FAQ preview
   - dedicated FAQ page
   - support pages reusing grouped FAQ blocks
   - canonical city-page dark-band FAQ accordions

   KEEP IN THIS FILE
   - .faq-list base accordion styles
   - .faq-list--dark dark-theme FAQ variant
   - .faq-heading grouped FAQ section heading
   - .faq-list--cards boxed FAQ-page / support-page card layout
   - .faq-list--lined city-page dark accordion variant
   - FAQ summary / details / paragraph internals
   - shared responsive behavior for FAQ modules

   DO NOT PUT IN THIS FILE
   - outer section shell layout like .faq-grid
   - intro-column spacing like .faq-intro
   - broad band spacing or section padding
   - page-only copy spacing tweaks
   - unrelated support-page layout wrappers

   OWNERSHIP NOTES
   - If the selector styles the accordion itself, it belongs here.
   - If the selector positions the intro column beside the FAQ block, it belongs
     in bands.css.
   - If a page needs a one-off FAQ presentation, add a modifier or page override
     rather than editing the base module.
