# Start a throwaway Radicale (a small CalDAV server) for the live tracker suite (Gitea #156).
#
#   start-radicale.sh <python-with-radicale> <work-dir>
#
# Radicale runs as a background process, not a service container: the jobs that call this
# already run inside a job container, and a process on 127.0.0.1 needs no network wiring.
# Appends the CHEMENU_LIVE_CALDAV_* variables to $GITHUB_ENV, so the pytest step that follows
# runs the CalDAV half of the live suite - with CHEMENU_LIVE_REQUIRE=caldav set by the
# workflow, so a server that did not come up fails the run instead of skipping it.
