Krzysztof kuhy Rudnicki d502580e3f Dark wallpaper rotator: new style every 3 h
Six text-free styles (gradient, flow/Voronoi, habit heatmap, shutdown
clock, Earth day/night, plasma) replace the white i3 root. A 15-minute
systemd user timer picks a new random style per monitor every 3 hours,
unlike its previous one and the other monitor's; live styles refresh in
between. Also syncs i3/config with the live config and prunes the
oldest evidence artifact for the 60-file cap.

# Workout screen locker. Same reason as the line above: the unit is
# WantedBy=graphical-session.target, and if i3 does not activate that target
# the login run never happens -- which on 2026-08-30 left the machine
# unenforced from a 14:06 reboot until the next timer tick. The run is
# idempotent (its early-exit ladder handles "already logged", "weekly minimum
# met", "window still active"), so starting it here as well costs nothing.

# LeetCode gate. Same reason again: WantedBy=graphical-session.target is not a

# Book gate (book-guard). Same reason as the two above: WantedBy=graphical-
