Objective

Introduces a new Range utility. It provides a convenient abstraction for working with numerical intervals, making it easier to perform interpolation and other range-based operations across the codebase.

Solution

Added a new Range class which:

• Supports defining a numeric range with start and end values.
• Provides a valid() method to ensure the range is properly ordered (start <= end).
• Implements lerp() to interpolate between start and end using a normalized value.

Showcase

Defining and interpolating over a range:

const r = new Range(0, 10)

console.log(r.valid()) // true
console.log(r.lerp(0.5)) // 5

Migration guide

No breaking changes introduced.
