/* ==========================================================================
   Chatsifieds shared components  (v20261113-ds2)
   Built only from --ds-* tokens (chatsifieds-tokens.css), so every component
   works in light and in opt-in dark mode.

   Generic:  .csf-btn (--primary | --commerce | --outline)  .csf-card
             .csf-tag (--use | --understand | --careful)  .csf-sponsor
             .csf-ring (progress)
   Scoped:   body.pw-page  = Phrase Wall phrase and category pages (these used
             to carry a duplicate inline <style> block plus Tailwind-CDN body
             classes; both are replaced by this file).
   Colour roles: commerce (ochre) is for sponsors/offers only.
