/* =========================================================================
   Bounce Back Smart — public pages served by the API (/for-trainers,
   /for-clinics, /affiliates).

   This is the marketing site's design system (bouncebacksmart.com,
   styles.css in the Netlify site source) reduced to the components these
   pages use, so a visitor arriving from the site sees the same site. The
   tokens in :root are copied verbatim from the site; if the site retunes its
   palette, retune this block the same way.

   Served at /public-assets/site.css — on the marketing domain that path is
   proxied to the API, so the same file works on both hosts.
