# Install all Python dependencies from the canonical requirements file.
# Previously the Dockerfile had a manually-maintained pip list that diverged
# from backend/requirements.txt on three packages:
#   diffusers 0.25.0 (Dockerfile) vs 0.32.0 (requirements) — CVE-flagged
#   python-multipart 0.0.22 vs 0.0.29
#   Pillow 12.1.1 vs 12.2.0
# This single-source approach also adds pillow-heif (HEIC/HEIF support)
# which was present in requirements.txt but missing from the Dockerfile.
