ARCANGEL0/ResumeMe ? reverse-engineered prompt

Build me a modern resume builder web app where someone can type in their info on one side and instantly see a polished resume preview on the other.

I want it to feel simple and fast, with a clean landing page, an editor for personal details and sections like experience, education, skills, and projects, plus the ability to add, remove, and reorder sections easily. Include several resume templates so the user can switch styles like modern, classic, minimal, and professional, and make sure the templates are ready for printing on A4.

Please also add language support for multiple languages across the whole app, save the resume automatically in the browser so it stays after refresh, and let the user export the finished resume as a PDF with one click.

Use a polished responsive design and keep the code organized and easy to extend, since I may want to add more templates later. If you need to check current docs for any libraries or PDF export details, look them up online.
