## What are Slots?

Slots let you target specific parts of consent components with styles. Each component is built from named slots such as `consentBannerTitle` and `consentDialogTag`.

Use slots after the stock component APIs and design tokens:

* If the change is semantic, prefer tokens first. For example, the stock banner footer background comes from `theme.colors.surfaceHover`.
* If the component part is correct but you need a local tweak, use a slot.

Common banner slot choices:

* `consentBannerCard` for card radius, shadow, width, and local background treatment
* `consentBannerFooter` for spacing, borders, and local footer styling
* `consentBannerTitle` for title typography
* `buttonPrimary` and `buttonSecondary` for shared button classes

## Using Slots

Pass slot styles in the theme's `slots` object:

```tsx
const theme = {
  slots: {
    consentBannerFooter: 'border-t border-black/10 px-6',
    consentBannerTitle: 'text-xl font-bold tracking-tight',

    // Object value = className + inline styles
    consentBannerCard: {
      className: 'rounded-xl shadow-lg',
      style: { maxWidth: '600px' },
    },
  },
} satisfies Theme;
```

## Slot Style Types

Each slot accepts either a `string` (treated as className) or a `SlotStyle` object:

```tsx
// String: treated as className
consentBannerTitle: 'my-custom-class'

// Object: className + style + noStyle
consentBannerFooter: {
  className: 'border-t border-black/10',
  style: { paddingBlock: '1rem' },
  noStyle: false, // Set true only when you want to remove this slot's default styling
}
```

`noStyle` on a slot is an advanced escape hatch. Start with className and style overrides first.

## Example: Style the stock banner without changing markup

```tsx
const theme = {
  colors: {
    surface: '#fffdf8',
    surfaceHover: '#f6f3ee',
  },
  slots: {
    consentBannerCard: 'rounded-[28px] shadow-xl',
    consentBannerFooter: 'border-t border-black/10 px-6',
    consentBannerTitle: 'tracking-tight',
  },
} satisfies Theme;
```
