Generated: do not edit. This directory is built by
\`tools/sieve-playground/build.sh --admin\` in inbuxa-server, from commit
\`$commit\`$dirty, with the server's vendored sieve-rs $version. Change the
source there, rebuild, and commit the result here.

The WebAssembly module is that commit's \`tools/sieve-playground\` crate, built
for \`wasm32-wasip1\`; its source, and the site's, are in that directory under
