Re:Parse, Don't Validate and Type-Driven Design in Rust

This exact philosophy is why I started treating UI design systems like compilers.
Instead of validating visual outputs after the fact (like linting CSS or manual design reviews), you parse the constraints upfront. If a layout component is strictly typed to only accept discrete grid multiples, an arbitrary 13px margin becomes a compile error, not a subjective design debate. It forces determinism.
