 - The workflow copies `index.html` to `404.html` so client-side routes keep working on repository Pages hosting.

+- The Playwright browser suite must run in its own `dotnet test` step after the supporting test projects, not inside a solution-wide parallel test invocation, because the suite self-hosts shared WASM assets on a dynamic loopback origin.
