This surface runs WebAssembly that is built by a separate, heavier workflow
(pages-wasm.yml, artifact wasm-cards). The build this site was
assembled from did not carry it, so the page it would have served does not exist here.
Nothing stale is being shown to you — the surface is simply absent.
Expected artifact wasm-cards; source: none-available.
What this build DID include, and exactly where its WebAssembly came from, is recorded in wasm-provenance.json and rendered at wasm-provenance.html.
