   ByteNet Digital CRM — design system
   Built around the ByteNet electric-blue mark, in two themes.

   Every colour lives in a token. The dark palette is the default on
   :root; [data-theme="light"] restates the same token names with
   light values, so no rule below needs to know which theme is on.
   Add a colour here, not in a rule, or the light theme won't follow.
