# --- THE MAGIC FIX ---
# This forces Streamlit to print "http://localhost:8501" instead of "0.0.0.0"
RUN mkdir -p /root/.streamlit
RUN bash -c 'echo -e "[browser]\nserverAddress = \"localhost\"\nserverPort = 8501" > /root/.streamlit/config.toml'
# ---------------------

# Copy the app code
COPY . .

# Expose the port
EXPOSE 8501

# Run the app
# Note: We still bind to 0.0.0.0 internally so Docker works, but the config above fixes the display.
