# App Screen (Moonarc)

A phone app's screen drawn from rows instead of a screenshot: a status bar, a title, then rows of fourteen kinds (a big figure, a ring of progress, a checklist, a bar chart, a card, chips, a map with a route, a player, a chat, a list, a week of days, a button, a lock screen's clock, a notification) and a tab bar. Without its chrome it draws a widget, a lock screen or a watch face. It sizes itself to the box it sits in with container units, so inside PhoneFrame it scales with the phone, and it takes its colours from the theme and the colour block it names, so a palette recolours every screen. As it arrives the ring fills, the bars grow, the route draws and the checks tick in, once; inside a Reveal they wait for it. One accessible name for the whole screen, or hidden as decoration. Zero JavaScript.

- Import: `import AppScreen from '@moonarc/core/AppScreen'`
- Install: `npx astro add moonarc` · copy-paste: `npx shadcn@latest add https://moonarc.dev/r/app-screen.json`
- Tier A · category ui · trigger load
- Readout: `<AppScreen title="Today" rows={[{ kind: "ring", … }]} />`
- Browser support: widely (Chrome 105 · Firefox 110 · Safari 16); elsewhere: without container units the screen keeps the page's text size and its rows stack as they are

## Props

| Prop | Type | Default | Description |
|---|---|---|---|
| `rows` | `Row[]` | none | The rows, top to bottom. Each has a kind: figure { label, value, note? }, ring { value 0–1, label, text }, checks { items: { text, done?, meta? }[] }, bars { values, labels?, highlight? }, card { title, text?, tag?, block? }, chips { items, active? }, map { label?, seed? }, player { title, meta?, progress 0–1 }, chat { messages: { from: me | them, text }[] }, list { items: { title, meta?, value? }[] }, days { label?, days: a string of x (done) and . (not) }, button { text }, clock { time, date? }, notice { app, title, text?, time? }. |
| `title` | `string` | none | The screen's title, large, under the status bar. |
| `eyebrow` | `string` | none | A small line over the title: a date, a greeting. |
| `tabs` | `{ label: string; icon: Icon }[]` | none | Up to five tabs at the foot. icon is one of home, chart, list, user, search, plus, bell, book, moon, map, chat or wallet. |
| `active` | `number` | `0` | The tab marked as current. |
| `block` | `1 | 2 | 3 | 4 | 5` | none | The colour block the accent takes (the ring, the done checks, the chips, the buttons); unset, the theme's primary. A card can name its own block. |
| `time` | `string` | `'9:41'` | The clock in the status bar. |
| `label` | `string` | none | What the screen shows, for a screen reader. Unset, the screen is decoration and hidden from assistive technology. |
| `chrome` | `boolean` | `true` | The status bar. false draws a widget or a watch face: the rows edge to edge, at the size of the box. |

## Usage

```astro
<PhoneFrame width="17rem">
  <AppScreen
    eyebrow="Friday 9 October"
    title="Today"
    block={1}
    label="The app's today screen: three of four habits done and a six-day streak"
    rows={[
      { kind: 'ring', value: 0.75, text: '3 of 4', label: 'habits done' },
      { kind: 'checks', items: [{ text: 'Walk 20 minutes', done: true }, { text: 'Read 10 pages', done: true }, { text: 'No phone after 10', done: true }, { text: 'Water the plants' }] },
      { kind: 'days', label: 'This week', days: 'xxxxxx.' },
    ]}
    tabs={[{ label: 'Today', icon: 'home' }, { label: 'Stats', icon: 'chart' }, { label: 'You', icon: 'user' }]}
  />
</PhoneFrame>
```

## Reduced motion

The screen is drawn as it ends: the ring full to its value, the bars grown, the route drawn, the checks ticked.

## With ClientRouter

CSS only; a fresh page draws the screen again.

## Craft

- Every length is a share of the screen's width (container units), so the same rows read the same on a 14 rem phone and a 22 rem one, the way a real screen scales with its device.
- A screen is a picture of the app: one accessible name says what it shows, and its rows are not read one by one. Without a label it is decoration and hidden.
- The accent is one colour (the block's, or the primary) and the ground is the page's: a palette change repaints the screen with the site.
- The motion is the app's own, once: progress filling, bars growing, a route drawing, a check landing. Nothing loops beside the copy.
- Every length is a share of the screen's own width through one unit, --ma-as-u (1cqi): a widget or a watch face sets it higher around the screen and the same rows draw larger for their box.
- Inside a Reveal that has not arrived the motion is paused, delay included, so a screen far down the page fills as it is scrolled to. --ma-as-at, set on the screen or above it, delays it further: a section that shows its screens in turn sets each one's moment.
- A seed draws the map's route, so the same screen draws the same way on every build.

## Replaces

- App screenshots on a landing page
- Device mockups with static screenshots
