The tabs difference does not reproduce at f61e893 against upstream/main built in its own worktree, so nothing is waiting on a decision. Records the instruction counts, frame times and memory taken today rather than mid-branch, and what a one-pixel line and a one-pixel gap do under the chain, which is the question the pixel difference was really about.
