  );
}

## 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 { ScaleIn } from "./system";

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

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

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>;
}

function Icon() {
    return <div style={{ width: 160, height: 160, background: lime, borderRadius: 38, ...center, boxShadow: "0 25px 60px #0002" }}><svg width="92" height="92" viewBox="0 0 92 92"><path d="M14 46 38 22 38 46 62 22 62 70 38 70 38 46 14 70Z" fill={ink}/></svg></div>;
}

export function ScaleInExample() { return <Stage dark><ScaleIn at={0.4} duration={1} from={0.35}><Icon /></ScaleIn></Stage>; }
```

Save it as src/ScaleInExample.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 { ScaleInExample } from "./ScaleInExample";

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

## Agent instructions

Use the 20cuts ScaleIn component in this project's Remotion composition. Introduce the product mark by scaling from 0.8 to 1 with a simultaneous fade; use a short, purposeful entrance. 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.
