Fedora Kinoite – What does this do?

I can't get through the marketing speak or pronounce the name, can someone tell me in plain english what this does and how it differs from Silverblue? There's a silverblue logo and a coreOS logo, but I was under the impression CoreOS was gone or sunset, and silverblue is still around.

Also, is silverblue supposed to be fedora + flatpak and flatseal?

Is this supposed to be a Nix-like thing?

It's workstation Fedora CoreOS with KDE as the desktop environment.

Fedora CoreOS is like regular Fedora, except it uses atomic rpm-ostree as the package manager and many directories are mounted read-only.

Pleased to see a KDE counterpart to Fedora's "immutable" GNOME desktop (Silverblue).
