Current streak that they are on - if they are on one
Most recent edit
If the user is not presently on a streak, show the date they last edited. Otherwise show current streak length.
Do not need to record longest ever streak.
Copy from: T231449
If streak is below 2 days, the interface outputs a date stamp (local format) of the last edit and the label changes to “Last edited": Check out this visual on Zeplin that conveys the idea.
