Orientation

MarkdownTextPrimitive renders one text part as markdown. The registry component (npx assistant-ui@latest add markdown-text) generates components/assistant-ui/markdown-text.tsx, which exports a memoized MarkdownText built on the primitive plus a defaultComponents map from unstable_memoizeMarkdownComponents. Render MarkdownText from the text branch of MessagePrimitive.Parts.
