You are an expert AI web developer and UI/UX designer. I want you to create a fully-featured, mobile-first NeuroScreen web app for smartphones that is low-cost, ultra-lightweight, and ideal for rural or low-resource areas. Generate complete HTML, CSS, and JavaScript with a modern, clean, and user-friendly design. Include comments for each section and placeholders for AI integration via serverless functions.

**Features and Screens:**

1. **Home Screen**
- App title: "NeuroScreen" with a modern, colorful header
- Buttons: Cognitive Test, Speech Test, Eye Tracking Test, Tremor Test, Results
- Attractive UI with icons and responsive layout
- Quick instructions for first-time users

2. **Cognitive Test Screen**
- Mini-games:
- Memory recall: show a sequence of numbers/images
- Reaction-time test: tap screen when color changes
- Animated transitions and progress bars
- **AI Integration Placeholder:** Call OpenAI GPT (via serverless function) to analyze responses and provide detailed feedback
- Display feedback in a visually appealing format (cards or alert boxes)

3. **Speech Test Screen**
- Record 5–10 seconds of audio or upload file
- **AI Integration Placeholder:** Use OpenAI Whisper or AssemblyAI to transcribe and analyze speech
- Visual waveform display while recording
- Animated feedback or icons for detected abnormalities

4. **Eye Tracking Test Screen**
- Use **device front camera** for eye-tracking
- Display a moving dot for user to follow
- Instructions: "Keep face centered, allow camera access"
- Camera settings: front-facing, 640x480, auto-start on screen load, stop on exit
- Placeholder for AI analysis detecting abnormal saccades or delayed pupil response
- Visual feedback on eye tracking (colored dot or progress bar)

5. **Tremor Test Screen**
- Ask user to hold phone still for 10–15 seconds
- Use accelerometer (DeviceMotionEvent) for tremor detection
- Animated visual guide showing how to hold the phone
- Placeholder for AI tremor analysis and real-time feedback

6. **Results Screen**
- Summarize all tests (Cognitive, Speech, Eye, Tremor)
- Display recommendation: Normal / Abnormal / Refer to Specialist
- Include visual charts or colored indicators
- Option to save results locally or share with a health worker

**UI/UX and Design**
- Modern, colorful, and clean mobile-first interface
- Responsive layout for all smartphones
- Smooth animations, transitions, and interactive buttons
- Clear instructions on each screen
- Color scheme suitable for easy readability in bright or low-light conditions
- Use icons, progress bars, and alerts to enhance feedback

**Working Conditions**
- Low-bandwidth friendly
- Offline placeholders for tests where AI integration is not available
- Simple and intuitive for non-specialist health workers
- All test data stored locally in browser storage (localStorage)
- Serverless API calls for AI integration (free OpenAI/AssemblyAI) with placeholders

**Technical Requirements**
- Single-page application or modular HTML/CSS/JS
- Include **placeholders for AI API calls**
- Comment each section to explain functionality
- Minimize external libraries; prefer pure HTML/CSS/JS
- Support modern mobile browsers (Android/iOS)
- Include camera and accelerometer permissions prompts where needed

**Output**
- Generate a **ready-to-run mobile web app**
- Include **all screens, navigation, animations, camera access, AI placeholders, and attractive UI/UX design**
- Comment each section clearly for future AI integration and deployment
- Initial Deployment

+You are an expert AI web developer and UI/UX designer. I want you to create a **fully-featured, mobile-first NeuroScreen web app** for smartphones that is low-cost, ultra-lightweight, and ideal for rural or low-resource areas. Generate **complete HTML, CSS, and JavaScript** with a modern, clean, and user-friendly design. Include comments for each section and placeholders for AI integration via serverless functions.
+**Features and Screens:**
+1. **Home Screen**
+   - App title: "NeuroScreen" with a modern, colorful header
+   - Buttons: Cognitive Test, Speech Test, Eye Tracking Test, Tremor Test, Results
+   - Attractive UI with icons and responsive layout
+   - Quick instructions for first-time users
+2. **Cognitive Test Screen**
+   - Mini-games:
+     - Memory recall: show a sequence of numbers/images
+     - Reaction-time test: tap screen when color changes
+   - Animated transitions and progress bars
+   - **AI Integration Placeholder:** Call OpenAI GPT (via serverless function) to analyze responses and provide detailed feedback
+   - Display feedback in a visually appealing format (cards or alert boxes)
+3. **Speech Test Screen**
+   - Record 5–10 seconds of audio or upload file
+   - **AI Integration Placeholder:** Use OpenAI Whisper or AssemblyAI to transcribe and analyze speech
+   - Visual waveform display while recording
+   - Animated feedback or icons for detected abnormalities
+4. **Eye Tracking Test Screen**
+   - Use **device front camera** for eye-tracking
+   - Display a moving dot for user to follow
+   - Instructions: "Keep face centered, allow camera access"
+   - Camera settings: front-facing, 640x480, auto-start on screen load, stop on exit
+   - Placeholder for AI analysis detecting abnormal saccades or delayed pupil response
+   - Visual feedback on eye tracking (colored dot or progress bar)
+5. **Tremor Test Screen**
+   - Ask user to hold phone still for 10–15 seconds
+   - Use accelerometer (DeviceMotionEvent) for tremor detection
+   - Animated visual guide showing how to hold the phone
+   - Placeholder for AI tremor analysis and real-time feedback
+6. **Results Screen**
+   - Summarize all tests (Cognitive, Speech, Eye, Tremor)
+   - Display recommendation: Normal / Abnormal / Refer to Specialist
