Waiting to load the WASM build (1.7 MB, about 700 KB compressed)

The browser runs renderAllBytes(input, "dot", "svg") on the same bytes the C reference read. WASM uses the portable math library, not Apple's libm, so a layout that depends on the last bit of sin or pow can legitimately differ (why).

The two hashes differ even when the outputs are identical, because each file keeps its own generator comment. Made by scripts/site-samples.sh.
