Ascendara/ascendara ? reverse-engineered prompt

Build me a desktop app called Ascendara for Windows and Linux that makes game management way easier. I want it to help people discover supported games, download them in just a couple clicks, and keep everything organized in one place without needing to extract, move, or install files by hand.

The app should have a clean home screen, search, game details with artwork and info, a downloads view, and a library where users can launch games. It should also support themes, local indexing for fast search, cloud backups for saves, browser integration for sending downloads directly into the app, and a couch friendly big picture mode. If it fits, include a retro section for older console games too.

Make it feel polished, easy to use, and available in lots of languages. If you need current docs or examples, look them up online first.
