Key notes

• Uses Vercel AI SDK provider setup with ThinkFeel’s OpenAI-compatible base URL.
• ThinkFeel completions are non-stream. The UI expects complete reply responses.
• ThinkFeel personify uses the native /api/v1/personify JSON endpoint.
• Tool-calling and some OpenAI parameters remain unsupported.
• Error responses are grouped as validation, config, or provider errors.
• If overriding THINKFEEL_BASE_URL for this OpenAI-compatible cookbook, include /api/v1.
• For ThinkFeel SDK or CLI setup, use the origin only.
• Legacy CURVE_* environment names remain fallback-only.
• New setup should use THINKFEEL_* names.
