IEvangelist/blazorators ? reverse-engineered prompt

Build me a C# solution for Blazor JavaScript interop that gives me strongly typed wrappers around browser APIs, so I can call JavaScript from Blazor without hand writing a lot of glue code.

I want it to support both Blazor WebAssembly and Blazor Server, with a clean DI friendly service style, and a source generator that can turn TypeScript style declarations into C# interfaces and callable methods. It should include ready to use packages for common browser features like local storage, session storage, geolocation, speech synthesis, speech recognition, and permissions, plus a broader DOM interop layer if that fits.

Please also include a couple of simple sample apps or demos that show how someone would register the services and call them from a Blazor page. If you need to check current .NET or Blazor docs while building it, go ahead and look them up online.
