The whole appliance UI is now configuration for a desktop Debian already ships: a Plasma 6.3 session with a colour scheme, a look and feel package that builds the bar, window rules, and KDE's own Kiosk restrictions. Two things were measured rather than assumed, and both changed a decision. Plasma restarts a crashed panel three times a minute and then gives up, which is the failure a classroom has already had. Four lines of systemd drop-in make it unconditional; the panel then survived eight SIGKILLs a second apart, back each time in 2.4s. Plasma draws a minimised task and a background task identically, so the five states the room needs cannot all be shown. Rather than write a task manager, the classroom removes minimise: clicking a launcher always means show me this. Co-Authored-By: Claude Opus 5 <[email protected]>

# Plasma's own unit already restarts plasmashell on a crash, but it gives

# up after three restarts in sixty seconds and the panel is then gone until

# machine has already had once, with the old hand-written dock, which had

# Measured in the lab: with these four lines, plasmashell survived eight

# consecutive SIGKILLs one second apart and came back every time in about

# 2.4 seconds. Without them it was permanently gone on the third.
