Recreate the "Workout Detail Screen" screen in React Native using LumioUI.

Goal: Workout hero with exercise list and start 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 add health-workout-detail
```

Or pull just the components: `npx lumioui add button glass icon image list text`

Native packages:
- @lumioui/ui@latest
- @lumioui/core@latest
- react-native-safe-area-context@*
- react-native-reanimated@*
- react-native-svg@*
- nativewind@*

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

## Components — how, where, when

### `button` — Tactile pill button with press spring, ink wash and async loading.
- `<Button>` ×2

### `glass` — iOS 26 liquid-glass surface — real glass via expo-glass-effect (Expo Go) or @callstack/liquid-glass (dev builds), SVG refraction + specular rim on web, frosted fallback elsewhere; GlassContainer melts adjacent panes into one blob
- `<Glass>` ×1

### `icon` — Lucide icon set mapped to theme colors and sizes.
- `<Icon>` ×3

### `image` — Cached image with placeholder, fallback and aspect handling.
- `<Image>` ×1

### `list` — Settings-style rows with separators and press feedback.
- imported but not rendered directly — likely used through a sibling or as a utility

### `text` — Themed type scale from caption to display.
- `<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/health/workout-detail.tsx` exporting WorkoutDetailScreen. Preserve the props interface — the host app wires the callbacks (navigation, submit handlers) through them.
