On swap-back Hyprland brings DP-1 up normal, binds a workspace to it, then apply
mirrors DP-1 — trapping that workspace on a layout-excluded mirror (unreachable;
symptom: 'can't make workspace 1 show'). apply now moves any workspace off a
mirrored output onto the headless primary. Verified the heal operation
(move-off-mirror) manually.
