Docker Image bauen und veröffentlichen / docker (push) Successful in 23m3s
Alpine lacks shared-mime-info, so file extensions with no built-in Go mime type (ODF, OOXML, epub, ics, ...) fall back to content sniffing and are served as "application/zip", breaking Collabora/DAVx5 on Android. Switch to debian:bookworm-slim and install shared-mime-info. Also install wget for the /healthz healthcheck instead of curl.
