# the single clearest way a settings app feels smaller than it is, and it
# regresses invisibly: nothing breaks, results just quietly stop appearing.
#
# This pins that every schema entry is reachable by its own label, that
# shortcuts are searchable by what they do, and that results route to a page
# that actually exists.
