# (ticket 521, ^du_report(16)) The whitespace of every panel, before and after, on one machine per job: 0.0.204 (^du_report(5)'s
# version), main where the branch left it, each commit of knoll-521 and its head, all served side by side, measured by one
# instrument (this branch's tools/checks/knoll521.mjs, FULL=1). Three jobs, the builds in a different order in each: layout does not
# depend on the machine's speed, so the three should agree to the pixel; how far they differ is the noise floor the report states.
# On a diag-521* branch only (never merged): tests and speed workflows git rm'd there.
