-## Running on Ubuntu 24.04+ without FUSE2
+## Ubuntu consumer behavior
 
-Some fresh Ubuntu installs do not include `libfuse.so.2`, so direct AppImage execution may fail.
+CI now publishes exactly one executable artifact per architecture:
 
-Use one of these options:
+- `electron_tray_demo-linux-<arch>-run<run>.AppImage`
 
-```bash
+This file is a self-launching wrapper that runs the packaged AppImage with
-# preferred package on Ubuntu 24.04+
+`APPIMAGE_EXTRACT_AND_RUN=1`, so it works on fresh Ubuntu systems even when
-sudo apt-get update && sudo apt-get install -y libfuse2t64
+`libfuse.so.2` is not installed.
-
-# then run AppImage normally
-./electron_tray_demo-linux-<arch>-run<run>.AppImage

-Or run without installing FUSE:
-
-```bash
-APPIMAGE_EXTRACT_AND_RUN=1 ./electron_tray_demo-linux-<arch>-run<run>.AppImage

-CI artifacts also include a convenience launcher:
