A real, installable Linux distribution built on Alpine, with a full KDE Plasma desktop and a graphical installer -- not a browser demo, an actual OS you boot and install.
A real Alpine Linux base -- musl libc, OpenRC, apk -- not a from-scratch distro.
A modern, familiar taskbar-and-start-menu desktop, not a bare console.
A real installer wizard -- disk selection, user setup, network -- no manual partitioning required.
The ISO you boot is just a lightweight installer -- the full system downloads over the network during setup.
