olivedapp/olived — reverse-engineered prompt

Build me a modern app called OlivedPro that works like a TV recorder for livestreams. I want to paste in a streamer link, have the app check if they are live, and automatically start recording as soon as the stream goes online. It should save the best quality available, anywhere from 720p up to 4K if my internet can handle it.

Please make it feel simple for normal users. I should be able to add favorite streamers, see who is online or offline, choose a download folder, start or stop recordings, and record more than one livestream at the same time.

It should support the big platforms shown in the project info, including YouTube, Twitch, TikTok, Bigo, Sooplive, Douyin, Douyu, Huya, Bilibili, AfreecaTV, Pixiv, YY, and adult webcam sites like Chaturbate, Stripchat, Cam4, and BongaCams. Let me add cookies when a site needs login access.

Make it cross platform if possible, and look up current streaming site behavior online if you need to.
