## Customization Patterns

### Tune ColorPanels colors and motion

Use shader override props without forking the component:

```tsx
<HeroColorPanelsRoot
  desktopShaderProps={{
    width: 1280,
    height: 720,
    colors: ["#ed40b3", "#6ef7cc", "#adfa1e", "#b054de"],
    colorBack: "#ffffff00",
    density: 5.03,
    angle1: 0.68,
    angle2: 0.28,
    length: 1.13,
    edges: true,
    blur: 0.25,
    fadeIn: 0.85,
    fadeOut: 0.3,
    gradient: 0.56,
    speed: 4,
    scale: 0.96,
    rotation: 180,
  }}
  mobileShaderProps={{
    colors: ["#ed40b3", "#6ef7cc", "#adfa1e", "#b054de"],
    speed: 4,
    scale: 0.96,
  }}
>
  {/* compose primitives */}
</HeroColorPanelsRoot>
```

### Swap hero copy and CTA

Replace copy and CTA target via props:

```tsx
<HeroColorPanelsRoot
  title="Your Product"
  subtitle="Ship faster"
  description="Reusable hero primitive with configurable ColorPanels visuals."
  ctaProps={{
    label: "Get started",
    href: "/signup",
    target: "_self",
  }}
>
  {/* compose primitives */}
</HeroColorPanelsRoot>
```

### Compose with slot primitives

Use primitive exports for custom layout composition:

```tsx
<HeroColorPanelsRoot>
  <HeroColorPanelsContainer>
    <HeroColorPanelsContent>
      <HeroColorPanelsHeading />
      <HeroColorPanelsDescription />
      <HeroColorPanelsActions />
      <HeroColorPanelsBadges />
    </HeroColorPanelsContent>
    <HeroColorPanelsVisual
      desktopShaderProps={{ colors: ["#006CFF", "#00d2ff"] }}
    />
  </HeroColorPanelsContainer>
  <HeroColorPanelsMobileVisual />
</HeroColorPanelsRoot>
```

## Performance Notes

- `ColorPanels` is wrapped with `memo` to avoid unnecessary rerenders.
- Mobile and desktop effects are rendered as separate sections so each layout can be tuned independently.
- Keep the hero in client-rendered regions only (`"use client"` is required).

## Accessibility Notes

- Includes a screen-reader-only heading (`sr-only`) so page structure remains meaningful.
- CTA link includes `rel="noopener noreferrer"` when opened in a new tab.
- Ensure visible contrast remains sufficient if you change shader colors or text opacity.

## Troubleshooting

### Shader does not render

- Confirm `@paper-design/shaders-react` is installed.
- Verify this component runs in a client context.
- Confirm parent containers are not clipping to zero height.

### Layout looks crowded on small screens

- Increase the mobile shader container height.
- Reduce heading size classes or copy length.
- Move badges under the fold for dense hero content.
