Six-framework baseline

First run recorded in the current format. It measures commit a241573 plus the uncommitted benchmark-tooling cleanup, which moved server-rendered HTML out of the fingerprinted build output. There is no earlier run to compare against.

Build: release profile with Binaryen 132 `wasm-opt -O3` through `FUSOR_WASM_OPT`, pinned wasm-bindgen 0.2.105, installed Chrome, framework order seeded with `BENCH_SEED=20261004`.

Recorded 2026-09-22T19:28:46.386Z on Apple M4 Pro, darwin 24.5.0, browser 153.0.8010.53, 15 samples after 3 warmups.

Every timed operation passed its correctness checks, and the source and artifact receipts matched before and after measurement.

Limitations: one local machine, 15 samples per row with the maximum as P95, no CPU or network throttling, and Chromium-only timings. Values under 0.10 ms are below the browser clock's resolution. Gzip sizes are per file at level 9, excluding headers and Brotli.
