Users can upload a photo of a coffee bag or type a text prompt to
auto-fill roaster/roast form fields via OpenRouter's chat completions
API. The feature is opt-in: hidden when BREWLOG_OPENROUTER_API_KEY is
not set.
- Add src/infrastructure/ai.rs with OpenRouter client, prompt
templates, JSON extraction from model responses, and unit tests
- Add extract-roaster and extract-roast API endpoints behind auth
- Add extraction UI (photo button + text input) to both form templates
- Add openrouter_api_key and openrouter_model to CLI args and AppState
- Enable reqwest gzip feature for compressed API responses
- Default model set to openrouter/free (auto-selects available models)
- Prompts instruct model to use web search for missing details
