# Kafe Nusantara — Hugging Face Space Dockerfile
# ══════════════════════════════════════════════════════════════
#
# This is a lightweight version for HF Spaces that runs the
# Next.js app in demo/static mode. The full infrastructure
# (PostgreSQL, Qdrant, Ollama, TEI) should be run locally
# or on a proper cloud setup.
#
# For HF Spaces, this builds and serves the Next.js app
# with demo/mock data (no external services required).
