⚠️ Benchmark changes need a look

🟢 0 better · 🔴 9 worse · ⚪ 6 noise (<±5%) · 0 without baseline

Compared against main 70c2114 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.
