# The SPC leader: every builtin also has a KEY PATH, and SPC walks it. While a
# path is pending the active pane's tag shows it at its RIGHT edge (the `/`
# input's rule — state you can see — right-aligned so it never collides with
# the tail's builtins). `?` at any depth opens the Help builtin, listing what
# the prefix typed so far can still reach, into a +Help OUTPUT BUFFER (a file
# pane with no file behind it, like +Search). The paths, the Help lines and
# the execute dispatch are all folded out of ONE enum at comptime — so
# executing the WORD `Help` runs the same builtin the leader does.
