xrimi/mobywatel ? reverse-engineered prompt

Build me a simple web app that looks and feels like the Polish mObywatel app, with a mobile first layout and a few basic screens that let a user move around like they would in the real app.

I want a home screen, a login screen, a profile and documents area, a QR code screen, a services screen, and separate pages for things like ID card, driving license, student and pensioner IDs. It should feel polished on a phone, with a clean government style design, icons, cards, and smooth navigation between the pages.

Make it work as a small offline friendly web app too, so it can still load with a service worker and manifest. Use the existing HTML pages and assets if they fit, and keep the experience simple and realistic, with sample placeholder data instead of real backend features. If anything about the official app design or labels is unclear, look up current references online and match the general feel.
