# Environment variables with defaults
ENV NODE_ENV=production
ENV PORT=3000
ENV LOG_LEVEL=info
# libuv dispatches every async `ort.InferenceSession.run` through its
# worker pool. With the default of 4 workers the pool becomes the next
# bottleneck once we run an N>=4 ONNX session pool. Bump to 16 so the
# session pool, not libuv, decides parallelism. Compose / k8s can
# override at deploy time if a host has tighter limits.
ENV UV_THREADPOOL_SIZE=16

# Expose port

# Health check
