Contributor guide
Research direction
Reproduce the issue with Day.js 1.10.7 using dayjs.tz and a locally changed locale with weekStart set to 5, then compare it with the working global-locale behavior. Done means the local timezone and locale combination recognizes Friday as the first day of the week.
