What
Lower-priority mode now tells you different things when it starts fresh versus when it resumes ("Lower-priority mode is back on until your limit resets at ..."), explains the cooldown that follows waiting too long for spare capacity, and the off message now says how to turn it back on.
Details
Availability is unchanged; only the wording and the tracked reset time are new.
Evidence
Lower-priority mode is off. New messages wait for your usage limit as usual
