func Errors(log zerolog.Logger, mappers ...Mapper) errchain.ErrorHandler

Errors turns handler errors into responses: unreadable body 400, validation failure 422, then mappers, then an opaque logged 500.

func Logger(l zerolog.Logger, skip ...string) func(http.Handler) http.Handler

Logger logs one line per completed request. Requests to a skip path only log on a non-2xx status, so a poll loop does not flood the log.

type Mapper func(err error) (status int, body any, ok bool)

Mapper translates one API's own error types to a response; the first mapper to report ok wins.
