The user wants me to create a web application based on the detailed specification provided. The app should:
- Include a landing homepage accessible via QR code (the QR code itself can be generated later; I will make the main page available)
- Display a welcome message and instructions
- Provide a form for personal information input (name, age, gender, and possibly others)
- Include an ergonomic assessment using ROSA (using the existing ergonomic assessment form we created)
- Show recommendations based on ROSA scores and personal info
- Allow saving or displaying a summary of assessments.
I will create a single HTML file with:
- A landing homepage with welcome/instruction section
- A personal info form
- The ROSA ergonomic assessment form (from previous version with images)
- After assessment, show recommendations and summary
- Simple JS navigation between sections/pages
- Save data in localStorage for session persistence (client-side only)
- All inline CSS and JavaScript; no backend
- Add instructions/manual section as per requirements
I will now create this full single-page ergonomic assessment web app with the required features.
