# Multi-stage image for the FastAPI + LiveKit Agent backend using uv.
|
|
# - production: smallest runtime image with gunicorn/uvicorn worker
|
|
# - development: hot-reload friendly image with full toolchain
|
|
# - builder: installs dependencies once for reuse across stages
|
|
#
|
|
# Keep dependency definitions aligned with docs/architecture.md.
