Dockerfile

# ============================================================
#  Dockerfile — Hugging Face Spaces (Docker SDK)
#  Free tier: 16GB RAM, 2 vCPU
#  HF exposes only port 7860 — nginx routes both Flask apps
#
#  /          → Flask 5000 (gesture + emotion)
#  /avatar/   → Flask 5001 (speech-to-sign)
