ChatGPT/Claude-style LLM chat surface. Collapsible left sidebar with New chat, searchable thread history grouped Today/Yesterday/Previous 7 days/Earlier, account row. Centered conversation: empty state with suggested-prompt tiles, user/assistant turns with code-block rendering and copy/regenerate/feedback actions, streaming dots, stop button. Composer with model picker (Opus/Sonnet/Haiku), attach, Enter-to-send, autosizing textarea. Stateful demo — wire `send()` to your streaming endpoint.
