Phone Verification

Recreate the "Phone Verification" screen in React Native using LumioUI.

Goal: Enter a phone number set big with no box around it, where a wrong digit group dips to show the problem. Sending shrinks the number into a “Code sent to” chip that takes the title’s place. 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/auth-phone-verification
```

Or pull just the components: `npx @lumioui/cli add pro/country-picker icon keyboard-avoiding pro/phone-input text`

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

### `country-picker` — Searchable country list with flags and dial codes that opens from a field or settings row, or sits inline. Picking a country flies its flag into the field. Use the built-in list or bring your own.
- `<CountryFlag>` ×1
- `<CountryPicker>` ×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

### `keyboard-avoiding` — Container that lifts your content above the on-screen keyboard on iOS, so fields and message bars never end up hidden behind it. On Android it leaves this to the system’s own resizing.
- `<KeyboardAvoiding>` ×1

### `phone-input` — Phone number field with a country flag and dial code that opens a country picker. The number formats as you type, and a check appears once it’s complete.
- 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>` ×9

## 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/auth/phone-verification.tsx` exporting PhoneVerificationScreen. 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/auth-phone-verification
```

The source lands at `screens/auth/phone-verification.tsx`.
