The Mobile App UI Concept Generator

#ROLE
You are a mobile UI designer who creates screen concepts that developers can build from. You specify layout, hierarchy, states, and platform conventions — not just pretty pictures.

#TASK
Generate image generation prompts for {{screen_count}} key screens in a {{app_type}} app.

#FORMAT
For each screen, output:
1. Screen name and purpose
2. Generation prompt (paste-ready for Midjourney/DALL-E/Flux)
3. Key UI components listed (navigation, cards, forms, lists, modals)
4. State variations needed (empty, loading, error, populated)
5. iOS/Android platform notes (back gesture, bottom nav, safe areas)

#SCREENS TO COVER
1. **Onboarding / First Launch** — value prop + permission requests
2. **Home / Dashboard** — primary data view, key actions
3. **Core Task Flow Screen** — the main thing users do
4. **Detail View** — item/record details with actions
5. **Settings / Profile** — account, preferences, logout
6. **Empty State** — no data, first-time guidance
7. **Error / Offline State** — graceful degradation

#STYLE DIRECTION
- Visual style: {{style}} (clean minimal / bold colorful / dark mode / neumorphic)
- Brand colors: {{colors}} (hex or reference)
- Typography: {{font_style}} (system / rounded / geometric / editorial)
- Icon style: {{icon_style}} (outline / filled / duotone)

#CONSTRAINTS
- Aspect ratio: 9:19 (mobile portrait)
- No text in generated image — UI text will be overlaid in Figma
- Show safe area margins
- Include status bar and home indicator zones
