 - Stylus-based frontend stylesheets now come from the `packages.${system}.appimageCss` derivation; `build_css.sh` simply copies that output, and `appimagePayload` pulls the same artifacts, so the AppDir no longer depends on ad-hoc `node_modules` during assembly.
 - `appimagePayload` now stages the launch scripts (`bin/ct`, `bin/ruby`, `AppRun`), config/resources, and the Ruby recorder submodule directly; `build_appimage2.sh` just handles impure steps (installing Ruby/Electron, copying `node_modules`, updating `frontend_bundle.js`, and calling `appimagetool`).
 - Third-party frontend assets that were previously symlinks into `node_modules` (`@exuanbo`, `golden-layout/dist`, `monaco-editor/min`, `mousetrap`, `vex-js`, `xterm`) are now materialized from `node-modules-derivation` inside `appimagePayload`, preventing broken symlinks when the payload is copied out of the Nix store.
+- Ruby 3.3 comes from `appimageDeps` (via `pkgs.ruby_3_3`) and is patched inside the derivation, so the AppDir no longer copies Ruby from the devshell during the AppImage build.
