# 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 caddy/playbook.yml has
# not run.
#
# The marker is the same one the retired nginx-menu playbook wrote per hostname,
# so a Site cut over from it has its block replaced in place rather than a second
# block for one address appended, which would make Caddy refuse the whole config.
