What ⏞ means
It marks a span from above.
An overbrace in a formula can group terms or hold a note such as “three terms”; the math layout system sizes it to the marked expression.
In earlier math printing, separate brace pieces from older font standards were assembled into tall braces around multi-line formulas. ⏞ is a different, horizontal delimiter.
