PCBoyGames/PillowDear-KDE6-Splash — reverse-engineered prompt

Build me a KDE Plasma 6 splash screen theme centered on PillowDear, with a cute polished indie VTuber vibe. I want it to feel like a real desktop startup screen, not just a static image, so use smooth QML based animation, clean timing, and a nice loading sequence that feels soft and cozy. The theme should be packaged so I can drop it into Plasma and select it as my splash screen without extra fuss.

Please make sure the visuals are cohesive and high quality, with sensible defaults for different screen sizes and a layout that stays centered and readable. If there are any theme metadata files or preview assets needed for KDE to recognize it properly, include those too. Keep the project focused on being a working Plasma 6 splash screen theme for PillowDear, and look up the current Plasma 6 splash theme docs online if you need to verify the right format.
