Gsap Utils

A solid collection of GSAP's math and array helpers, straight from GreenSock's official skills repo. You'll reach for this when you need to clamp scroll values, map progress ranges to rotation degrees, snap draggable elements to a grid, or randomize stagger delays. The function-form pattern is clever: omit the last argument and most utils return a reusable function you can call repeatedly without reallocating (random is the exception, it uses a true flag). Distribute is the sleeper hit here, it handles complex value spreading across arrays or grids with easing curves, which saves you from writing gnarly index math by hand. Works anywhere in your animation pipeline, not just in tweens.
