A layered image editor for Linux and Omarchy, ported from Compositor (github.com/robbietilton/Compositor), whose Swift source is its specification. It reads and writes Compositor's .comp projects. Packages for Ubuntu, Fedora and Arch come from the release workflow; scripts/install/ holds one install script per distribution family, and flake.nix serves NixOS.
