/* ============================================================
   Synogram Cloud — marketing stylesheet

   Tokens are copied from the app's app/globals.css and the type/spacing
   scales from DESIGN-SYSTEM.md §3-4. This file is the landing project's
   copy of the contract: the app and the landing deploy separately, so the
   values are duplicated here on purpose.

   If a token changes in app/globals.css, change it here too.
   Never introduce a hex value that is not in DESIGN-SYSTEM.md.
