/* ============================================================
   Kada public site — one stylesheet for the landing page and the
   legal documents.

   The app's own palette: white ground, near-black text, Kada yellow
   only on the call to action and small accents. DM Sans throughout,
   matching the app shell. Deliberately small — the site says three
   things, so it does not need a design system to say them.
