Composable validation
// I could not find any validation library (zod, io-ts etc) that allows custom error types
// so quickly wipped this up, note that the errors here are string literals but they
// might as well be, say, custom classes for pattern matching later
// think about error messages that you need to translate to many languages in the front-end
