# ─────────────────────────────────────────────────────────────────────────────
# DevAI Studio v4.9.2 — STORAGE-OPTIMIZED Dockerfile
# Target: Hugging Face Spaces (CPU basic, 50 GB free storage)
#
# Key changes vs original:
#   1. Ollama is NOT installed at build time (~150 MB saved).
#      It installs lazily inside entrypoint.sh on first Private Mode request.
#   2. NO local model weights are pre-bundled (~22 GB saved).
#   3. Same Python + framework stack as original — all functionality intact.
# ─────────────────────────────────────────────────────────────────────────────
