Tag v2.6.1, commit 7f9f17d6012f404e83bbf0f931a4d06eb4af465b
Build script: build.sh, which incorporates src/masker_stub.c and embeds
vendor/primer3/src/primer3_config into the generated WebAssembly.
The large kmer_lists and native upstream test data are not used by the build;
masker support is explicitly omitted by this WASM adaptation.
Emscripten SDK version used for the published binary is unknown. The default
build script uses latest. Exact byte-for-byte reproducibility is not verified.
The published binary is unmodified and its SHA-256 is below.
