## Complete example

This is the source of the fictional component demonstration. Replace its content
with supported behavior and assets from your product.

```tsx
import React, { type CSSProperties, type ReactNode } from "react";

import { AbsoluteFill } from "remotion";

import { RuleDraw } from "./system";

const ink = "#141414", lime = "#b6f36b";

const center: CSSProperties = { display: "flex", alignItems: "center", justifyContent: "center" };

const large: CSSProperties = { fontSize: 104, lineHeight: 1.06, fontWeight: 700, letterSpacing: "-0.055em" };

function Stage({ children, dark = false, style }: {
    children: ReactNode;
    dark?: boolean;
    style?: CSSProperties;
}) {
    return <AbsoluteFill style={{ fontFamily: "Arial, Helvetica, sans-serif", color: dark ? "#fff" : ink, background: dark ? ink : "#f7f7f5", ...center, ...style }}>{children}</AbsoluteFill>;
}

export function RuleDrawExample() { return <Stage><div style={{ width: 890 }}><div style={{ ...large, marginBottom: 34 }}>Make it clear.</div><RuleDraw at={0.7} duration={1.1} width={885} thickness={12}/></div></Stage>; }
```

Save it as src/RuleDrawExample.tsx. This demonstration uses
1280×720, 30fps and 180 frames.
For a separate entry point, replace src/index.tsx with this registration, then
run npm run studio:

```tsx
import { Composition, registerRoot } from "remotion";
import { RuleDrawExample } from "./RuleDrawExample";

registerRoot(() => (
  <Composition
    id="RuleDrawExample"
    component={RuleDrawExample}
    width={1280}
    height={720}
    fps={30}
    durationInFrames={180}
  />
));
```

## Agent instructions

Use the 20cuts RuleDraw component in this project's Remotion composition. Draw a single underline beneath the headline's key phrase, starting after the words land. Keep motion frame-driven and put timing in seconds relative to the current Sequence. Use the product's actual copy and assets. Preview the composition before rendering.
