EasingExtensions

Evaluates an easing function at normalized time t (typically 0..1), matching how Unity UI Toolkit / web (CSS) easings behave: - Linear, ease, ease-in, ease-out, ease-in-out use CSS cubic-bezier curves. - The named Sine/Cubic/Circ/Elastic/Back/Bounce use the same standard formulas you’ll find in common web easing references (e.g., easings.net style).
