⚠️ Benchmark changes need a look

🟢 1 better · 🔴 6 worse · ⚪ 8 noise (<±5%) · 0 without baseline

Compared against main 2c2c0e5 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.
