# Typography (Lumen Halo): prompt.md (v1.0.0)

- id: `lumen-typography` · version 1.0.0 · component · free
- category: Text & motion
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add https://beautiful-ui.dev/r/lumen-typography.json`
- npm dependencies: none
- registry dependencies: utils, https://beautiful-ui.dev/r/lumen-foundation.json
- docs: https://beautiful-ui.dev/components/lumen-typography
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

Long-form text in Lumen's voice: wrap docs, release notes, Markdown or chat answers in Prose and plain HTML takes a quiet hierarchy, bullets drawn as small lit cells, a filament beside quotes, and mono readouts for code and numbers.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: none beyond React.
- Files: `components/ui/lumen/typography.tsx`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `lumen-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: `Prose`, `Lead`, and every exported type.
- CSS: the install merges this item's rules (the registry `css` field) into your global stylesheet, in `@layer components`, and adds the lumen foundation (tokens, keyframes, motion levels) 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 `--lumen-*` custom properties (`--lumen-accent`, `--lumen-accent-text`, `--lumen-bad`, `--lumen-bad-text`, `--lumen-focus`, `--lumen-good`, `--lumen-good-text`, `--lumen-hairline`, `--lumen-ink`, `--lumen-muted-ink`, `--lumen-series-1`, `--lumen-series-2`, `--lumen-series-3`, `--lumen-series-4`, `--lumen-series-5`, `--lumen-series-6`, `--lumen-warn`, `--lumen-warn-text`); this item's CSS also reads `--lumen-font-mono`, `--lumen-font-sans`, `--lumen-radius-k`. Never add Tailwind colour classes inside the component.

```tsx
import { Lead, Prose } from "@/components/ui/lumen/typography";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `Prose` | `prose` | The long-form wrapper. |
| `Lead` | `prose-lead` | Opening paragraph. |

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 `GlassSoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/glass-sound.json`, import from `@/components/beautiful-ui/glass-sound`); `GlassSoundToggle` is its mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/lumen/typography.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
- typography, prose, markdown, rich text, article, docs page, release notes, blog post, chat answer, shadcn typography, Lumen
- Rendered Markdown or MDX
- Docs, changelogs, help articles
- Long AI answers

### Not when
- Interface labels and short UI text: those come with each component

## Mistakes
- Keep Prose for long-form text; don't wrap app UI in it
- Let the measure (68ch) stand: long lines tire the eye

## Usage

```tsx
import { Lead, Prose } from "@/components/ui/lumen/typography";

<Prose>
  <h1>Lumen, spring release</h1>
  <Lead>Story charts, saved views and a faster explorer.</Lead>
  <MDXContent />
</Prose>
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `Prose` | `div` |  | Wrap long-form HTML; every element inside takes Lumen type. |
| `Lead` | `p` |  | The larger opening paragraph. |

## Customising
- Colours: set the `--lumen-*` tokens on `:root`, or on a container with the `lumen-scope` class to retheme one area. Add the `lumen-inherit` class to follow your shadcn palette instead (`--chart-N`, `--destructive`).
- 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://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| — | Links inside are focusable |

## Motion inventory

| Interaction | What moves |
|---|---|
| None | Still, as text should be |

## Accessibility contract (preserve when editing)
- Plain semantic HTML; headings keep their levels
- Links are underlined, not colour alone

## Install

Base UI project (a base-* style in components.json):

```bash
npx shadcn@latest add https://beautiful-ui.dev/r/lumen-typography.json
```

Radix project (a radix-*, new-york or default style):

```bash
npx shadcn@latest add https://beautiful-ui.dev/r/radix-nova/lumen-typography.json
```

Or add the `@beautiful-ui` registry to components.json and run `npx shadcn@latest add @beautiful-ui/lumen-typography`: the CLI picks the build from your style.

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