Promo Codes

Recreate the "Promo Codes" screen in React Native using LumioUI.

Goal: Apply discounts from a wallet of perforated coupon tickets, led by a big ticket showing your total before and after. Applying a code tears its stub and stamps it; codes that can’t apply say why. 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/ecommerce-promo-codes
```

Or pull just the components: `npx @lumioui/cli add button pro/countdown pro/coupon-input icon input text`

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

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

## Components — how, where, when

### `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

### `countdown` — Live countdown with rolling digits, inline or as blocks that brighten through the final ten seconds. At zero it can celebrate and show your result, or quietly fade if time ran out.
- `<Countdown>` ×1

### `coupon-input` — Promo and gift code field that turns into a perforated ticket showing your saving when the code works, and explains why when it doesn’t. The ticket also works on its own for coupon wallets.
- `<CouponInput>` ×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>` ×3

### `input` — Labelled text field that lights up on focus, draws a check when you mark the value as good, and gives one quick flicker on error. Supports helper text, icons and a fill-as-you-type underline.
- imported but not rendered directly — likely used through a sibling or as a utility

### `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>` ×24

## 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/ecommerce/promo-codes.tsx` exporting PromoCodesScreen. 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/ecommerce-promo-codes
```

The source lands at `screens/ecommerce/promo-codes.tsx`.
