Applied as-is. Captured real battles live in public/dev/perf (including the round-13 联防 on the wide round battlefield), with a browser speed page and a headless benchmark. public/dev stays out of the package. The Chrome benchmark was not run. The numbers in the original pull request are from 0.1.4 and are not quoted here.
Tests: node --test test/perfbench.test.js test/render/battle-perf.browser.test.js — 13 pass, 0 fail; the Chrome suite skipped (RENDER_E2E unset).
