+# Packaging de l'app de bureau Electron, déclenché UNIQUEMENT par un tag desktop-vX.Y.Z (séparé de
+# la release du daemon qui écoute v*, et du VSIX qui écoute vscode-v*). Linux (AppImage + deb) est
+# automatisé ici ; Windows et macOS se buildent sur ces OS (voir packages/desktop/README.md) et
+# leurs artefacts sont attachés manuellement à la release.
