/* ==========================================================================
   SwiftFAQ Accordion – ADA/WCAG 2.1 AA Compliant Styles

   All visual values are driven by CSS custom properties (--swiftfaq-*).
   Defaults below are the fallbacks used when a property is not set from the
   SwiftFAQ Settings screen, so the plugin looks identical until a setting is
   changed. The settings page only emits variables for values you actually set.
