/* =========================================================================
   Beziworld React Theme — interactivity layer.
   Presentation for the Interactivity API modules: mini-cart drawer,
   quick-view modal, loading/busy states, the sticky add-to-cart bar, and the
   screen-reader-only helper used by aria-live regions. This is the last
   author layer before utilities, so it owns the chrome that overlays the
   page. Tokens come from base.css; this layer never redefines them.

   Open/closed state is driven by the modules through data-wp-class--is-open
   directives, so styling keys off the .is-open class rather than inline
   styles. Motion is suppressed under prefers-reduced-motion.
