The saggar-dist chart: a single-node Garage hosting the distribution
bucket — public read-only website on get.saggar.dev (the host label
is what Garage's vhost routing resolves the bucket from), S3 write
surface staying cluster-internal for the publish workflow. Same edge
path as the other saggar hosts: dns A record, cert-manager
certificate, caddy route. Chart repo and packages auth carry over
from the saggar release.
