 Routes can return errors to indicate that something wrong happened. Ideally, the error is of type `*echo.HTTPError` to indicate the intended HTTP response code.

-The [error handler](https://echo.labstack.com/guide/error-handling/) is set to a provided route `pkg/handlers/error.go` in the `BuildRouter()` function. That means that if any middleware or route return an error, the request gets routed there. This route conveniently constructs and renders a `Page` which uses the template `templates/pages/error.go`. The status code is passed to the template so you can easily alter the markup depending on the error type.
