This looks promising! The "no IDL required" approach is nice compared to gRPC or tRPC.

How does Tygor handle complex Go types like time.Time, custom JSON marshalers, or embedded structs? I've used similar tools (tygo, guts) and often run into edge cases with these.

Also curious about the performance overhead - is there any benchmarking data on the RPC layer vs direct HTTP handlers?

The Vite plugin with hot reload is a great DX touch.
