   VK-Innovation  ·  Ergänzungen zum Cassiopeia-Template
   --------------------------------------------------------------------------
   Datei ablegen unter:
       media/templates/site/cassiopeia/css/user.css
   Joomla lädt sie ab Version 4.1 automatisch, es ist nichts weiter zu tun.
   Sie bleibt bei Joomla-Updates erhalten, weil Cassiopeia sie nicht
   überschreibt.

   Regel für diese Datei: alles Eigene ist mit "vk-" benannt. Nur die
   wenigen Blöcke unter "Cassiopeia anpassen" greifen in das Template ein,
   und zwar so sparsam wie möglich.

   Keine externen Ressourcen. Keine Webfonts. Nichts, was nachgeladen wird.
