#
# waybar's hyprland/language module styles as #language and nothing else: it
# has no per-language CSS class, so a flag cannot be selected by a selector.
# format-<lang> exists but takes text, not a path. So the flag arrives the
# same way every other icon on this bar does, through an `image` module.
#
# wb-lang # print "$path\n$tooltip" for the image module
#
# The flags live next to this bar's config because the icon theme ships 13 and
# neither Italian nor British is among them.
