- AQ_DRM_DEVICES=/dev/dri/card0 forces Aquamarine to use only the
Intel iGPU, avoiding EGL_BAD_MATCH errors from the NVIDIA RTX 3060
after VT/DPMS cycles (page-flip lockups, black display)
- lock.sh: guard against duplicate hyprlock instances (second instance
steals surfaces, leaves screen black)
- lid-close.sh: same guard for laptop
- wake-display.sh: conditional DPMS cycle (only when display is off)
to restore hyprlock surfaces without flicker
- unstick-display.sh: emergency recovery script for tty3
