Blocking the very first real deploy of the sandbox: base/deployment.yaml
referenced an imagePullSecrets entry ("ghcr-pull") that was never created,
which fails pod startup regardless of whether the image needs auth at
all - kubelet errors trying to resolve the named secret before it gets
anywhere near actually pulling.
Confirmed by execution (anonymous GHCR token, pull succeeded) that
ghcr.io/brvncde-dotcom/vncmail-plus-dev is public. Removing the block is
deploy/k8s/README.md's own documented alternative for exactly this case.
