UniqueTomm/Rewind-Launcher-V4 ? reverse-engineered prompt

Build me a clean desktop launcher app called Rewind Launcher V4 for personal use.

I want a modern, polished interface that feels fast and simple, with a left side navigation, a main home screen, and a few useful sections like news, settings, and profile. Make it look good in a dark theme, with subtle accents, smooth transitions, and a layout that works well on different window sizes.

Keep it focused on the launcher experience itself, not on connecting to any external game or service accounts. I just want the app shell, navigation, placeholder content, and a solid structure that can be extended later. If you need to check anything about the current setup or best practices, look up the latest docs online.

Please make the code clean, organized, and ready to run, with the UI styled nicely and the desktop app behavior working smoothly.
