"""Phase 0 (SPEC §12) — prove mapping quality before any art or UI.

Runs Agent 1 (the Deck Designer) against the open ≤32B model for several varied
themes and prints each deck as a readable archetype→concept table plus the full
JSON. Inspect by hand: do the mappings read as clever-but-right across all
themes? If not, fix the prompt/few-shots before building anything else.

Usage:
    set -a; source ~/tokens; set +a
    python -m scripts.phase0_mapping                 # default 5 themes
    python -m scripts.phase0_mapping "free jazz" "tax law"
