/**
 * BOB vs LLM — Side-by-Side Comparison
 *
 * Same task. Two systems. Completely different architectures.
 *
 * BOB:
 *   - QRNG → HolyC NIL → Emoji trigger → Prolog route → Ada gate → WORM seal
 *   - Cannot hallucinate: Ada gate blocks unverified output
 *   - Fully traceable: every step in WORM chain
 *   - Deterministic logic path: Prolog rules are constants
 *   - Genuine novelty: QRNG seeds each decision point
 *
 * LLM providers supported:
 *   groq     — Llama 3.3 70B via Groq LPU (fastest, free tier)
 *   gpt4o    — GPT-4o via OpenAI
 *   gemini   — Gemini 2.0 Flash via Google
 *   ollama   — Local Ollama (default, nemotron)
 *
 * Usage: node compare.mjs [task] [provider]
 *   node compare.mjs all groq
 *   node compare.mjs logic_chain gpt4o
