Food Cart

Recreate the "Food Cart" screen in React Native using LumioUI.

Goal: Food basket led by the arrival time, with rush, regular or pickup options, add-ons, tip and a clear receipt. Placing the order turns the button into its own receipt and locks in an exact time. Match the reference implementation's layout, behavior, and motion exactly — this is a production screen, not a mockup.

## Setup

Fastest path — install the screen plus its component deps:

```bash
npx @lumioui/cli add pro/food-food-cart
```

Or pull just the components: `npx @lumioui/cli add pro/add-to-cart-button animated-number button pro/cart-item empty-state icon image pro/lightbox pro/order-summary pro/swipeable-row text pro/tip-selector`

Native packages:
- react-native-reanimated@*
- react-native-safe-area-context@*
- react-native-svg@*

Stack assumptions: Expo SDK 54 / RN 0.81, Reanimated 4, NativeWind v4, TypeScript strict, Expo Go compatible.

## Components — how, where, when

### `add-to-cart-button` — Add button that becomes its own result: busy dots while adding, a check and “In bag”, then a quantity stepper with a trash icon at one. A compact version stretches open over product photos.
- `<AddToCartButton>` ×1

### `animated-number` — Number that moves to each new value as a calm count-up or a roll where only the changed digits turn, set in type or in dot-matrix LEDs whose dots switch on in place. Screen readers announce just the final value, not every step.
- `<AnimatedNumber>` ×1

### `button` — Pill button that presses down under your finger, in eight styles from solid to glass, with a built-in loading state that swaps in place while an action runs.
- `<Button>` ×1

### `cart-item` — Cart line with thumbnail, options, quantity stepper and line total. Removing an item offers a quick Undo before the row closes, and saving for later lifts the item away.
- `<CartItem>` ×1

### `empty-state` — Placeholder for empty lists, no search results and errors, with an icon, headline, short message and action. Soft light falls from the top as the content fades in.
- `<EmptyState>` ×1

### `icon` — Icon set drawn on one consistent grid, sized and coloured from your theme. The heart, star and bookmark can fill in place inside their outline, then fade back out.
- `<Icon>` ×5

### `image` — Image with a placeholder while it loads, a fallback when it fails, and aspect-ratio handling so your layout doesn’t jump when the picture arrives.
- `<Image>` ×2

### `lightbox` — Photo gallery where any tapped photo grows out of its exact tile into a full-screen viewer, then flies back into the tile of whichever photo is showing when you let it go.
- `<LightboxProvider>` ×1
- `<LightboxImage>` ×1

### `order-summary` — Checkout totals with subtotal, discount, shipping and tax, and a big total that counts to each new value. Applied promo codes show as removable chips.
- `<OrderSummary>` ×1

### `swipeable-row` — List row that swipes to reveal actions on either side. Pull far enough and the main action fills the row and runs when you let go; deleted rows fold away and only one row stays open.
- `<SwipeableRow>` ×1

### `text` — Themed type scale from caption to display that follows light and dark mode. Includes a pull-quote style with an accent rule and a quieter dimmed tone for secondary text.
- `<Text>` ×21

### `tip-selector` — Tip picker with percentage or fixed-amount options and a highlight that glides between them. An Other option opens a custom amount field for any tip you like.
- `<TipSelector>` ×1

## Conventions (non-negotiable)

- Styling via NativeWind `className` with semantic tokens only: `bg-background`, `text-foreground`, `bg-card`, `text-card-foreground`, `bg-secondary`, `bg-muted`, `text-muted-foreground`, `bg-accent`, `bg-destructive`, `border-border`. Hard-coded colors only inside media overlays (`text-white`, `bg-black/N`).
- Motion via the token presets from `@lumioui/core` (`spring.press`, `spring.surface`, `spring.glide`, `timing.fast`, `timing.slow`, …) — no bespoke spring configs or durations.
- Gate transform motion behind `useReducedMotion()`; keep opacity/color feedback, drop travel and overshoot.
- Haptics via `useHaptic()`: `light` on press, `selection` on toggle/select, `warning` on invalid input. Never import expo-haptics directly.
- Press feedback via `usePressAnimation()` (~0.97 scale), not `activeOpacity` tricks.
- a11y: `accessibilityRole` + `accessibilityLabel` on every control, touch targets ≥44pt.
- Entrance choreography: staggered `Mount` wrappers (delay 0/60/120…) so regions land in sequence instead of popping in at once.
- Wrap the screen in `SafeAreaView`; keep dark mode working via the semantic tokens.

## Deliverable

One file: `screens/food/food-cart.tsx` exporting FoodCartScreen. Preserve the props interface — the host app wires the callbacks (navigation, submit handlers) through them.

## Reference implementation

This is a LumioUI Pro item: its source is not published in the docs. Install it with a Pro license key
(set `LUMIO_LICENSE_KEY`; keys are on lumioui.com/account) and read the installed file as the reference:

```bash
npx @lumioui/cli add pro/food-food-cart
```

The source lands at `screens/food/food-cart.tsx`.
