Kant CMS: Grundgerüst, visueller Editor, Mediathek

Symfony 7.4 / Twig / Doctrine DBAL auf herkömmlichem PHP-Webhosting.
Versionierte Blockdokumente (v1-v3) mit unveränderlichen Revisionen,
getrennten Entwürfen/Veröffentlichungen und optimistischer
Konflikterkennung. Visueller Editor mit Strukturbaum, Live-Vorschau,
responsiven Gerätewerten, Abschnittsvorlagen, Bildmediathek,
Galerien und Effekten. Öffentliche Ausgabe ohne Editor-JavaScript.

Geprüft: 41 PHP-Tests / 155 Assertions, 10 JavaScript-Modelltests.
