AI chat-completions client - The OpenAI-compatible HTTP client in src/ai.rs — text completions offering the no_reply tool, image descriptions with the vision model (request text from vision.md), image validation, timeouts, retries with linear backoff, error handling, the optional request log and reply parsing.
Web control panel - The optional HTTP control panel in src/web.rs and src/web_page.html, enabled by web_port — routes, the custom-header guard on POST, the request/reply bridge to App through AppEvent::Web, the quit flow, the browser page and its security caveats.
WhatsApp client integration - How src/whatsapp.rs wraps whatsapp-rust — session startup, translation of raw events into WaEvent, JID canonicalization, contact names, history sync, message rendering, image download and sending.
