   anxiousdentist.co.uk — design system
   One stylesheet. Tokens first. No build step.

   Brief: the visitor is already anxious before the page loads. Nothing here
   should read as clinical, urgent or shiny. Warm paper, sage green, soft clay.
   Generous line-height, large comfortable type, slow and minimal motion.
   Deliberately unlike humanoconsulting.co.uk (Newsreader/Inter, teal) and
   alchemise.capital (mono/black) so the brands never read as siblings.
