   Calyvento — calyvento.com
   Design tokens mirror the app's own palette (Calyvento/Design/VTheme.swift)
   so the site and the product read as one thing.

   No web fonts, no third-party requests: the page renders in the reader's own
   system typefaces. On a Mac — where the app lives — that is New York + SF Pro.
