🎮 Game

Goo is an immediate-mode UI library for s&box that gives games animated panels, text, images, SVGs, shaders, drag and drop, and HUD helpers. It builds a virtual tree of lightweight blob records, diffs it to a retained Fiber tree, then applies Ops to Sandbox.UI panels each frame, with style accumulation, state variants, and timeline/tween helpers. There is optional shader effect support with uniform bags and framebuffer grabs, plus small input and layout utilities.
