# M1 image — intentionally minimal (no torch / ffmpeg yet) so the first HF Spaces
# build is fast and reliable. M2 adds the ML stack + ffmpeg + baked fast weights.
FROM python:3.12-slim

# HF Spaces runs containers as a non-root user with UID 1000.
# Create /app owned by `user` BEFORE dropping privilege — otherwise Docker creates
# the WORKDIR root-owned and later writes (M2 weight baking) fail.
