Native systemd install (matches Ollama pattern on Arch — Docker on mRock
has no nvidia runtime; native venv via uv is the lighter path). The
Black-Forest-Labs FLUX.1-schnell HF repo is gated, so the download script
points at ungated mirrors (Comfy-Org/flux1-schnell + sirorable/flux-ae-vae)
that ship the same Apache-2.0 weights.
First image — cat in a fishbowl, 1024x1024, 4 steps — generated end-to-end
in 9.79s via curl + workflow JSON; stored at
/home/m/dev/ImaGen/poc/first-image.png on mRiver (not committed; transient
PoC artefact). Go adapter is phase 2.
