/* ============================================================================
   av-faq.css — shared FAQ accordion styles (native details/summary, no Bootstrap).
   Extracted from av-exchange.css (2026-07-16, F214 item 4) so templates that
   are NOT on the /exchange/:id/ bundle -- starting with the homepage -- can
   render the same visible FAQ markup (.av-faq-section / .av-faq-item /
   .av-faq-body) without pulling in exchange-page-only CSS (hero, flow
   diagram, feature table). av-exchange.css keeps its own copy of these rules
   for /exchange/:id/; this file is the reusable subset for everyone else.
   Built on the same av-tokens + av-components variables. Monochrome + orange
   accent only. Day/night via data-theme.
