    On the inner edge the tenon has a small shoulder, which hides the
    mortise; on the outer edge the shoulder sets the mortise back from the
    end of the stile, and a haunch, a short, shallow continuation of the
    tenon, fills it in a haunch mortise running out of the stile's end, so
    the rail can't twist. Unlike `haunched_stub_tenon_corner` (no inner
    shoulder) and `stub_tenon_corner` (no haunch either).
