Clean cherry-pick — nothing here was edited by hand. It applied to release/v1.3 without conflicts, and the backported tree built green before #8806 merged.

Close this PR and reopen it to start its required checks. This pull request was opened by github-actions[bot], and GitHub starts no workflow run for anything the Actions token does, so it has no checks yet. Reopening it (or pushing any commit to the branch) emits the event they subscribe to. Marking it ready for review will not — none of the three required workflows listen for that.

After that: approve, and enable auto-merge if you would rather not come back when the checks finish.

⚠️ Benchmark changes need a look

🟢 2 better · 🔴 1 worse · ⚪ 12 noise (<±5%) · 0 without baseline

Compared against main 33b47a8 benchmarked on this same runner, so the delta is largely free of cross-runner hardware noise. The "7d avg" column still reflects the gh-pages dashboard. Treat <±5% as noise unless repeated.
