Eighteen branches on origin that the issue classifies as landed, or
superseded by merged pull requests, were deleted; the evidence for each
is on the issue. Four whose work is not in next are kept: the three
issue 87 error-display branches, reference for issue 493, and
chore/token-list-enrichment, re-created at f7a2437, pending issue 495.
TODO.md records this.
The branch-pruning Future Step had already left TODO.md in the issue 191
rewrite, so only the Completed Steps entry is added.
