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.
