Thanks — the comma you spotted is correct and has landed, in #224 together with the other two you reported.

Closing rather than merging because all three of these were built on a stale main. Each carried one genuinely missing comma plus two edits that are already there: the 240-second hyphen landed in #170, and does not depend is already the wording. So rebasing three PRs against the same file would have produced three near-empty diffs.

Credit is yours; the fix is in.
