# Every "open the settings for this" jump must land somewhere real.
#
# ShellState.openSettings() hands its argument to SettingsRoutes.resolve(),
# which falls back to Home for anything it does not recognise. That fallback is
# sensible and it is also completely silent: a typo, or a page renamed later,
# turns a right-click into "opens Settings on the wrong page" with nothing
# logged and no error.
#
# Before this, exactly four places in the entire shell could reach Settings, so
# the risk was small. The bar now offers a jump on every widget, which makes the
# fallback worth guarding.
#
# A jump may name either a leaf ("firewall") or a category ("network"), since
# resolve() opens a category at its first available tab. Anything else is a
# typo, and SettingsRoutes.qml is the only place that knows which is which.
