	# XDG_TOPLEVEL_WM_CAPABILITIES_SINCE_VERSION - "use of undeclared
	# identifier" on wlroots 0.20, not because ScrapLinux's xdg-shell.xml or
	# wayland-scanner are wrong (confirmed: wayland-scanner server-header
	# against ScrapLinux's own xdg-shell.xml emits both correctly, 54
	# SINCE_VERSION constants total), but because wlroots 0.20's installed
	# wlr_xdg_shell.h pulls its constants from
	# <wayland-protocols/xdg-shell-enum.h> - a *separate*, more limited
	# header wayland-protocols pre-generates with wayland-scanner's
	# enum-header mode, which only covers enum *value* constants, not
	# per-message SINCE_VERSION guards for events like configure_bounds.
	# dwl 0.8 predates this wlroots 0.19->0.20 restructuring and has never
	# been adjusted for it (confirmed no newer tagged release exists).
	# Defining the two guards locally, at their real xdg-shell protocol
	# version numbers (checked directly against the xdg-shell.xml ScrapLinux
	# ships: configure_bounds since="4", wm_capabilities since="5"), is
	# the same fix dwl.c's own client.h would need from any downstream
	# consumer hitting this - not something wayland-protocols or wlroots
	# themselves need to change.
