Word-level streaming animations — new animate attribute enables per-word fade-in during streaming, inspired by Vercel's Streamdown. Three built-in animations: fadeIn, blurIn, slideUp. Pure server-side — no JS hooks required.
```
<.markdown content={@response} streaming animate="fadeIn" />
```
Ship priv/static/phoenix_streamdown.css with animation keyframes. Include in your app:
```
@import "../../deps/phoenix_streamdown/priv/static/phoenix_streamdown.css";
```
