Unifast: a Rust markdown/MDX compiler 25x faster than remark/rehype

I built Unifast, a Rust-based markdown/MDX compiler.

In local benchmarks, it compiles about 25x faster than remark/rehype-based workflows.

I started this because I wanted a simpler and faster pipeline for markdown compilation, without carrying the complexity of multiple AST boundaries for common use cases.

It’s still early, so I’d love feedback on bugs, missing features, and real-world use cases.
