# Portable CPU image for the ProGress UI.
#
# Deploy targets:
#   • Hugging Face Spaces (Docker SDK) — set the Space SDK to "docker".
#   • Any container host (Render / Fly / a VM / local) —
#     `docker run --gpus all -p 7860:7860 …` (omit --gpus all for CPU-only hosts).
#
# requirements.txt pins torch 2.8 (CUDA build); it falls back to CPU when no GPU
# is present, so this image runs on both GPU and CPU hosts.  The primary target
# is a Hugging Face ZeroGPU Space (no Docker); this file is for self-hosting.
