/* ===========================================================================
   xventures.de — legal pages (Impressum, Datenschutzerklaerung)
   ---------------------------------------------------------------------------
   These pages carry statutory text, so the job of the design is not to be
   clever: it is to make a long German legal document genuinely readable, and
   to make the parts a regulator or a visitor is looking for findable in
   seconds. Tokens are inherited verbatim from index.html so the pages read as
   part of the site rather than as a generator's output pasted on the end.

   Everything here is self-hosted. No font, script or stylesheet leaves the
   origin. See netlify.toml for the CSP that enforces that.
