Signup

Recreate the "Signup" screen in React Native using LumioUI.

Goal: Create an issue-tracker account while the product listens, taking your company name and ticket prefix from your email. Signing up lifts your first issue out of the list and marks it In progress. 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-signup
```

Or pull just the components: `npx @lumioui/cli add avatar button icon input keyboard-avoiding password-strength 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

### `avatar` — Circular profile image with fallback initials and a presence dot. An optional mode shows presence on the photo itself, bright when online and faded when away or offline.
- `<Avatar>` ×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

### `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.
- `<Input>` ×3

### `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

### `password-strength` — Compact password strength meter for sign-up forms. Four bars light up as the password gets stronger, and common passwords are flagged straight away.
- `<PasswordStrength>` ×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

## 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/signup.tsx` exporting SignupScreen. 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-signup
```

The source lands at `screens/auth/signup.tsx`.
