Dockerfile

# Multi-stage Dockerfile for the MasterMode hosted demo.
#
# Stage 1 — build the React frontend (needs Node).
# Stage 2 — Python runtime with the Python deps + the dist/ artifacts
#   from stage 1. Final image runs `uvicorn lifeos.demo.server:app`.
#
# Designed for one-click deploy platforms (vibeops.tech, Fly.io, etc.)
# that auto-detect a Dockerfile. Free-tier-friendly: no torch /
# sentence-transformers, embeddings via Gemini API.
