AIChat (elements/ai/AIChat) is a complete LLM chat UI built on new hooks: - useAIChat: streaming conversation state (send, stop, regenerate, edit, feedback); `send` may return a string, async iterable, ReadableStream or fetch Response - useAIChatHistory: saved conversations with optional localStorage persistence and generated titles, shown in AIChatSidebar - useAIChatSpeech: read aloud via browser speech synthesis or a custom `speak` returning audio - useAIChatDictation: voice input via browser recognition or a custom `transcribe` Also adds a model picker, message editing, thumbs up/down, markdown export, scoped markdown styles in base.css, the twuiReadTextStream, twuiStripMarkdown and twuiGroupByRecency utils (with tests), and a playground page. AIPromptBlock is kept and marked deprecated. Co-Authored-By: Claude Opus 5.5 <[email protected]>
