Great work, thank you for sharing it!
A sample bundle is here: https://drive.google.com/file/d/13rW2bhnr8nxcEpRrVmLrd3P8K8-q-r6d/
The bundle is just a collection of static assets files, so it doesn’t require any special server infrastructure. But the hosting needs to allow to configure Content-Encoding headers. Many file types in a bundle are compressed and they need to be served with Content-Encoding: gzip header, otherwise browsers won’t decompress them correctly.
For example, if your hosting provider uses Apache server and allows you to set own .htaccess config file (most do), you can just use .htaccess file included in the bundle and the scene should load correctly.
