Streaming markdown renderer for Phoenix LiveView, inspired by Vercel’s Streamdown. Built to fully leverage LiveView — server-side rendering, DOM diffing, zero client-side JavaScript.

• Auto-closes incomplete markdown syntax mid-stream (bold, code fences, links, images)
• Block-level memoization — completed blocks get phx-update=”ignore”, only the last block re-renders
• 100+ syntax highlighting themes via Lumis
• GFM extensions (tables, strikethrough, task lists, autolinks)
• Drop-in component: <.markdown content={@response} streaming />
