SnipeOS 26.04 LTS (every app opened)
A complete first-run tour: every non-system application on the desktop launched on camera (SnipeOffice Writer through to Base, Kdenlive, Shotcut, OpenShot and OBS Studio importing real video; Ardour and Audacity ready to record; Blender on first launch; VLC and Kodi playing clips; SuperTux, Frozen Bubble, and Steam signing in without dependency work). Nothing is downloaded or configured beforehand.
USB pendrive preparation
How to write the SnipeOS ISO to a USB stick so the machine can boot from it.
Installation
Live boot through Calamares: welcome, partitions, user setup, the long pause while the system unpacks, then first reboot.
