🖼️ Feature Request — Profile Picture Upload

Feature	User Story	Acceptance Criteria
Profile Picture Upload	As a user, I want to upload or change my profile picture so that my generated resume includes a professional portrait	- User can upload an image file (JPG, PNG, or AVIF) up to 2 MB.- Image preview is displayed in the form and live resume preview.- The system validates file type, size, and aspect ratio (square preferred).- Uploaded image is stored temporarily (session-based, not persisted).- When generating the PDF, the backend fetches and embeds the image in the LaTeX template.- If no image is uploaded, the resume is generated without a profile picture placeholder.

Technical Notes

• Frontend:
  • Add FileUpload component (drag & drop + preview).
  • Convert uploaded file to base64 or pre-signed upload URL.
  • Integrate with existing personalInfo.profilePhoto field.
• Backend:
  • Accept optional profilePhoto field (base64 or URL).
  • Sanitize and validate MIME type and file size.
  • Temporarily write file to LaTeX compilation directory.
  • Embed in template via \includegraphics with scaling.

Security & Compliance

• Enforce strict MIME-type checking (image/jpeg, image/png, image/avif).
• Limit uploads to 2 MB per file, reject others with HTTP 413.
• No persistent storage (compliance with privacy-first MVP).

Future Enhancements

• Integration with user account system for persistent photo storage.
• Optional photo cropping and auto-scaling.
• AI-based photo optimization for lighting and background removal.
