/* ==========================================================================
   Dyvo — getdyvo.com design system

   One stylesheet for every page. The tokens mirror Theme.swift so the site
   and the app read as one product; when a palette token changes in the app,
   change it here too.

   No build step, on purpose: the site is deployed by dragging web/ into
   Cloudflare Pages, so anything that needs compiling is a way for the live
   site to fall out of sync with the repo.
