AI chat interface

A chat UI that posts the conversation to a backend endpoint you configure. No provider keys in the browser.

A complete chat front end: message list with user/assistant bubbles, Enter-to-send textarea, pending and error states, cancel with AbortController, and persisted history. It talks to a single configurable endpoint (VITE_CHAT_API_URL or a field in the header) using a documented JSON contract, and renders an explicit 'No backend configured' state until you point it at a server that holds the provider key. Pair it with the Express REST API template for the backend.
