Prime removed the second instance after the v0.1.3 bench. esh-ml1 handles a face
in ~48 ms, sits in the house next to the cameras, and holds the verified
backup. fv-ml1's gallery was empty (0 identities). The container, gallery volume,
image, compose dir (with its .env), backup dir and build sources are removed from
fv-ml1. GPU_ID / CARD_SUFFIX stay in the compose for any future second host.
