The overview page carried `docker run` invocations (including a CUDA variant, on a fleet with no
NVIDIA card left in it) and the `LLAMA_ARG_` environment rule, while `setup.md` — the page whose
own intro promises "build instructions, Docker, and systemd deployment" — carried the Compose
example and the same env form in use. Two places to look, one place to be wrong.
`setup.md` now states the env-prefix rule where the flags live (and why units prefer it: one
flag per line is auditable, a forty-flag command line is not), and the overview keeps only the
API surface and the GGUF format, pointing at the sections that absorbed the rest.
