# Append this site's block to the shared Caddyfile.
#
# The Caddyfile is a bind mount into the Caddy container, so Caddy sees the
# change as soon as the file is written; the handler only asks Caddy to re-read
# it. That is a reload, not a restart, so the other hosted sites are untouched.
#
# blockinfile is idempotent on its own via the marker, so there is no need to
# slurp the file and compare first — which also matters because slurp *fails*
# when the Caddyfile does not exist yet, on a host where the Caddy playbook has
# not run.
#
# The marker is stable, so re-runs replace this site's block in place rather than
# appending a second copy of it.
