jonbarrow/stream-box — reverse-engineered prompt

Build me a simple free desktop app for watching movies and TV shows. I want it to feel like a lightweight streaming box where I can search for a movie or series, open a result, pull in playable sources from the web, and start watching inside the app. It should handle both movies and episodic TV, show basic artwork and details, and keep the interface easy to use from a couch setup, with support for a media center style remote if that already fits.

Please make it work as a desktop app that can be packaged for Windows, Linux, and Mac. Keep it open source and straightforward rather than trying to turn it into a huge service. If anything is unclear, look up the current docs online and fill in the missing pieces in a sensible way.
