# keys-2k MiniMax-H3 Parallel — Two DGX Sparks (GB10 / aarch64)
# ComfyUI 0.31.1 + pinned Power Pack custom_nodes + quality launch flags.
# Models are NOT baked in — mount models/ at runtime (see docker-compose / fetch_weights.sh).
#
# Build on a DGX Spark (arm64) that already has a working h3-cotenancy tree, or use
# the published image: ghcr.io/drowzeys/keys-2k-minimax-h3-parallel-two-dgx-sparks
