# Testimonials (Notchset): prompt.md (v1.0.0)

- id: `testimonials` · version 1.0.0 · block · pro (Pro)
- category: Marketing
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @notchset-pro/testimonials`
- npm dependencies: class-variance-authority@^0.7
- registry dependencies: utils, https://notchset.dev/r/notchset-foundation.json
- docs: https://notchset.dev/components/testimonials
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A testimonial carousel backed by numbers: a greyscale 4:5 portrait with the company chip that wipes to the next in the direction of travel, the quote rising word by word with its key phrase underlined once it lands, the name and role, two proof rows with the struck-through before and rolling after, segmented progress bars that advance on their own and pause on hover, focus and PAUSE, and previous / next.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `class-variance-authority@^0.7`.
- Files: `components/ui/notchset/blocks/testimonials.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`, `lib/beautiful-ui/notchset/button-variants.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `Testimonials`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-glide`, `--notchset-ease-key-down`, `--notchset-ease-key-up`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-grow-to`, `--notchset-key-down`, `--notchset-key-up`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scan-to`, `--notchset-scroll`, `--notchset-sheet-from`, `--notchset-signal`, `--notchset-sweep-to`, `--notchset-travel`). Never add Tailwind colour classes inside the component.

```tsx
import { Testimonials, type Testimonial } from "@/components/ui/notchset/blocks/testimonials";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `Testimonials` | `testimonials` | Portrait, quote, proof rows and the carousel controls. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://notchset.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/blocks/testimonials.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- testimonials, customer quotes, reviews, case study carousel, social proof, wall of love, Notchset
- A landing page's customer voices, each with a measurable result
- Leading into case studies

### Not when
- Dozens of short quotes: use a grid
- Quotes without permission or numbers you can't stand behind

## Mistakes
- Use real customer headshots, not stock
- Keep the highlight an exact phrase from the quote

## Usage

```tsx
import { Testimonials, type Testimonial } from "@/components/ui/notchset/blocks/testimonials";

export function Voices({ items }: { items: Testimonial[] }) {
  return <Testimonials items={items} interval={8000} />;
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `items` | `{ id, name, role, company, quote, highlight?, proof, portrait }[]` |  | highlight is a phrase from the quote; proof rows are { label, before, after }; portrait { src, srcSet?, alt }. |
| `interval` | `number` |  | Milliseconds per quote (7000). |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://notchset.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| ← → | Previous / next story |
| Tab then Enter | Jump to a story, pause |

## Performance

- CSS animations only; two images in the DOM at a time.

## Responsive

- Under 720px (container width) the portrait sits above the quote, at most 320px wide.

## Motion inventory

| Interaction | What moves |
|---|---|
| Next story | The portrait wipes in from the direction of travel (720ms) |
| Quote | Words rise in 16ms apart; the key phrase's underline draws once they land |
| Progress | The bar fills over the interval, then advances |

## Accessibility contract (preserve when editing)
- A carousel (aria-roledescription) whose quote is a polite live region, read as plain text, not word by word
- Auto-advance stops on hover, focus and PAUSE; progress bars are buttons naming each story
- Portraits carry the person's name as alt text

## Install

```bash
npx shadcn@latest add @notchset-pro/testimonials
```

Pro item: needs the `@notchset-pro` registry in `components.json` and `NOTCHSET_TOKEN` in `.env.local` (https://notchset.dev/account). Setup: https://notchset.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://notchset.dev/r/notchset-foundation.json.
