## Guidelines

What customers say. One quote is set large and centred; several sit in a grid on the card surface.

### Use it when
- Real quotes from named people.

### Don't use it when
- Invented quotes. Leave the block out until you have real ones.

### Example
```jsx
<TestimonialBlock
  quotes={[{ quote: "Tokens made the redesign a config change.", name: "Ada Lovelace", role: "Design Systems Lead, Northwind" }]}
/>
```

### Stacking blocks
Blocks are Sections, so a page is a list of them. Alternate `tone` (base, subtle, base, brand) so one band ends where the next begins, keep one `HeroBlock` at the top and one `CtaBlock` at the end, and let everything between be the argument. Pass `dark` to scope dark mode to a single block.

### Title size
Set `titleSize` to move the title along the type scale, from `display-lg` down to `heading-md`. It defaults to `heading-lg`. Only its size changes: the heading level stays what the block renders.

### Tokens
Reads the section, typography and card tokens through `Section`, `Heading` and `Text`; it has none of its own. Retheme it by retheming those.

### Accessibility
Each block is a `<section>`. Give the page one `h1` (the HeroBlock's title) and let every other block's title be an `h2`, which is what they render.

## Props

```ts
import * as React from "react";

/** One quote in a TestimonialBlock. */
export interface TestimonialItem {
  quote: React.ReactNode;
  /** Who said it. Also the initials in the default avatar. */
  name?: string;
  /** Their role and company. */
  role?: string;
  /** A custom avatar; defaults to an Avatar from name. */
  avatar?: React.ReactNode;
}

/** What customers say: one quote set large, or several in a grid. */
export interface TestimonialBlockProps extends Omit<React.HTMLAttributes<HTMLElement>, "title"> {
  /** A few words above the title. */
  eyebrow?: React.ReactNode;
  /** The block's heading. */
  title?: React.ReactNode;
  /** The title's type size, on the system's heading and display scale. @default "heading-lg" */
  titleSize?: "display-lg" | "display-md" | "display-sm" | "heading-xl" | "heading-lg" | "heading-md";
  lead?: React.ReactNode;
  quotes: TestimonialItem[];
  /** The band's surface, passed to Section. @default "base" */
  tone?: "base" | "subtle" | "brand" | "brand-muted" | "secondary" | "secondary-muted";
  /** Scopes dark mode to this block, so everything inside reads light on dark. */
  dark?: boolean;
  /** Layers the texture token over the tone. */
  texture?: boolean;
  /** Padding above and below, passed to Section: `sm`, `md`, `lg`, `xl` or `none`, from the module padding steps; `default` is `md` and `compact` is `sm`. @default "default" */
  spacing?: "none" | "sm" | "md" | "lg" | "xl" | "default" | "compact";
  /** Padding above, when it differs from `spacing`. */
  spacingTop?: "none" | "sm" | "md" | "lg" | "xl";
  /** Padding below, when it differs from `spacing`. */
  spacingBottom?: "none" | "sm" | "md" | "lg" | "xl";
  /** `full` spans the screen; `inset` sets the band in from the page edges with the container radius. Passed to Section. @default "full" */
  bleed?: "full" | "inset";
  /** The inner column's width. @default "default" */
  width?: "narrow" | "default" | "wide" | "full";
}

export declare function TestimonialBlock(props: TestimonialBlockProps): React.JSX.Element;
```

## Tokens it reads

| Token | Tier | Declared as |
| --- | --- | --- |
| `--dt-card-bg` | component | `var(--dt-surface-raised)` |
| `--dt-card-border-color` | component | `var(--dt-border-default)` |
| `--dt-card-border-width` | component | `var(--dt-border-width-default)` |
| `--dt-card-fg` | component | `var(--dt-text-primary)` |
| `--dt-card-padding` | component | `var(--dt-space-inset-lg)` |
| `--dt-card-radius` | component | `var(--dt-radius-container)` |
| `--dt-layout-module-gap` | semantic | `var(--dt-space-stack-xl)` |
| `--dt-space-inline-lg` | semantic | `var(--dt-dim-6)` |
