MOBI / AZW / AZW3 support: MOBI import is included on Linux, arm64 macOS, and Windows. The arm64 macOS and Windows builds statically link libmobi, so no extra install is needed. Linux dynamically links against libmobi — install it before first MOBI open with
sudo apt install libmobi0(Debian / Ubuntu). EPUB / PDF / CBZ / CBR do not need libmobi. The x86_64 (Intel) macOS build does not include MOBI support — use a different format on that platform.
