/* chatterbox_csi_request_walkthrough_ver8.css
   The customer-service walkthrough. Loaded after chatterbox_csi_ver8.css and built on
   its tokens and its thread and figure classes; this sheet sets no colour of its own.

   Every rule is scoped under .rq8-stage, so the component can sit on any family page.
   Base styles are the finished state of each scene: the family sheet turns transitions
   off when motion is reduced, and the page must read in full without any script.
   Solid cards only inside the stage, and nothing here loops. */
