/* ============================================================
   krysion.css — the Krysion design language, shared base
   https://www.krysion.com/krysion.css

   Every Krysion site links this file, then its own stylesheet.
   The rules behind every value are in DESIGN.md (Krysion Website
   repo); when the two disagree, DESIGN.md wins and this file is
   fixed. A deploy of krysion.com restyles every site that links
   it, so changes here are gated like footer.js and cookies.js.

   A site sets   :root { --accent: #…; }
   (and --on-accent when the contrast rule in DESIGN.md §2.3 says so),
   and may set its own palette, DESIGN.md §2.16: the neutral and
   surface tokens below, with the same selectors, after this file.
   Dark theme: <html data-theme="dark">, or always-dark sites put
   class="theme-dark" on <html>.
