REPO_POLICIES.md requires cmd/ to be thin: one main.go whose body is a
single call into internal/ or pkg/. The image, the handler, the server
and their test move unchanged into internal/loadtestorigin, whose Run
does what main did; cmd/loadtest-origin/main.go only calls it.

script/loadtest [duration [clients]], or make loadtest, is a benchmark
that script/check does not run. It builds the image and vegeta from a
pinned commit, then for each scenario starts a new pixad container and
a new cmd/loadtest-origin container, an upstream host that answers every
path with one generated JPEG: a cached image (hit), a new source image
per request (miss), and each new source image asked for by all clients
at once (herd). It prints vegeta's report, pixad's peak resident memory
and the requests the origin got. The containers share a network in
203.0.113.0/24, as pixad refuses private and local upstream addresses.
README.md says how to run and read it; TODO.md records a small baseline.
