| Currently waybar _can_ try to start even if there's no graphical session (and
no sway) running. Adding `Requisite=` prevents this. From `systemd.unit(5)`:
    Requisite=
       Similar to Requires=. However, if the units listed here are not
       started already, they will not be started and the starting of
       this unit will fail immediately.  Requisite= does not imply an
       ordering dependency, even if both units are started in the same
       transaction. Hence this setting should usually be combined with
       After=, to ensure this unit is not started before the other
       unit.
       When Requisite=b.service is used on a.service, this dependency
       will show as RequisiteOf=a.service in property listing of
       b.service.  RequisiteOf= dependency cannot be specified directly. | ||
