Make the wiki UX reproducible: set_navigation writes the custom static sidebar
(Home + Anwender + Betrieb, betrieb items visible only to admin groups 1/3);
ensure_html_rendering turns on markdownCore.allowHTML (v-encoded, other renderer
configs preserved) so the HTML card landing renders — note it needs a Wiki.js
restart to take effect on a fresh instance. The injectCSS is rebuilt: content links
get an underline + accent (the old broad primary--text coloring made non-links look
like links) plus the landing card/button styles. Page content lives in git-storage.
