CRT idle screensaver for DSH pages: when no session is running and the page has seen no mouse or keyboard input for ten minutes (configurable), a retro CRT plate covers the window with scanlines and a looping inversion sweep. An in-window click or key press dismisses it, the wheel only locks scrolling, and the whole frame drifts slightly after the cursor; rendering is fully GPU-composited frame by frame. An adaptation of justawebsite/dsh-splash-crt (MIT), turned from a boot splash into an idle screensaver.
