- Button loading spinner + disable on submit to prevent duplicate AI calls
- Email field and opt-in consent checkbox on calculator form (checked by default)
- Privacy assurance blurb below opt-in
- Refinement blurb on results screen explaining live cash-flow optimization

- server.js: add /api/calculate endpoint using openai SDK with configurable
AI_API_URL, AI_API_KEY, AI_MODEL, AI_DEBUG env vars (works with any
OpenAI-compatible provider: NVIDIA NIM, Together AI, Groq, Ollama, etc.)
- app.js: make calculator submit handler async; call /api/calculate with
graceful fallback to client-side generated text if AI is unavailable
- package.json: add openai and dotenv dependencies
- AI_SETUP.md: rewrite to document new unified env var config with provider examples
