Roslyn source generator that reads .js/.d.ts modules and emits typed C# wrapper classes for Blazor JS interop. Supports JSDoc, TypeScript declarations, string literal union enums, and custom path resolvers. Zero runtime overhead — generates the same IJSRuntime.InvokeAsync calls you'd write by hand. PREVIEW: This package is under active development and used internally. The API may change between versions. No stability guarantees.
