# ROLE: deploy-vllm — orchestrator. Phased, idempotent, mirrors the pattern
# used by roles/llm-inference and roles/llm-inference-multimodel:
#   Phase 1: dependencies (Python/venv/vLLM/CUDA/nvidia-smi)
#   Phase 2: model downloads (~/.vllm-cache, checksum-verified)
#   Phase 3: systemd service(s)
#   Phase 4: API key management (1Password)
#   Phase 5: verification (health + smoke test)
# Each phase is a separate task file so a partial re-run / targeted --tags
# run is possible without re-reading the whole role.
