/// A value that is guaranteed to be normalized (between `0.0` and `1.0`).
///
/// Might be useful to avoid confusion in math-heavy code.
/// For example, a function might expect some of its arguments
/// to be normalized real numbers. Instead of just documenting
/// it in API docs or checking it at runtime, we can express it
/// through the parameter's static type.
///
/// This is an extension type. The nice thing about those is that
/// they have zero runtime overhead.
