# Tell wlroots to use the headless backend (no DRM master needed) and skip
# libinput device probing — there are no input devices on a real headless box.
# The Vulkan renderer is preferred on NVIDIA + handles NVENC capture cleanly;
# wlroots falls back to GLES2 automatically if Vulkan isn't usable.
