The work laptop drives two 3840x2160 panels, so a fixed 1920x1080 capture was being upscaled 2x on the client — fine for Big Picture's large UI, visibly soft for terminal text on the Desktop app. A headless wlroots output has no physical size, so it can take any mode. Both apps now set HEADLESS-1 to SUNSHINE_CLIENT_WIDTH/HEIGHT/FPS in their prep-cmd and restore 1920x1080 on undo. SWAYSOCK joins the environment import so Sunshine's prep-cmds can reach the compositor at all.
