# The Shortcuts page is generated from the compositor, so it cannot drift from
# the real keymap. Two things have to hold for that to be true:
#
# * every bind Hyprland reports is presented -- the page count matches
# `hyprctl binds -j` exactly, so adding a bind cannot silently go missing;
# * every bind carries a description. Hyprland reports Lua-defined binds with
# dispatcher "__lua" and a bytecode offset as the argument, so a bind
# without a description has nothing a person could read beside its chord.
# The service drops those rather than showing a mystery row, which means an
# undescribed bind disappears from the page -- this contract is what stops
# that from being a silent loss.
