# HF Spaces require user 1000 to avoid permission issues with the writable
# bind-mounts the platform sets up at runtime.
RUN useradd -m -u 1000 user
USER user
ENV HOME=/home/user PATH=/home/user/.local/bin:$PATH

# Install Python deps first so subsequent code changes don't bust the layer.
COPY --chown=user requirements.txt ./
RUN pip install --no-cache-dir --upgrade pip \
 && pip install --no-cache-dir -r requirements.txt

# Runtime sources only — admin/training scripts stay out of the deployed
# image to keep it small and reduce the attack surface.
COPY --chown=user main.py ./

# Must match app_port in README.md YAML so HF's edge routes to the right port.
