chocolate-bar2410/cinnamon-3D-UI ? reverse-engineered prompt

Build me a Roblox 3D UI framework called Cinnamon that makes it easy to create richer in game interfaces in both world space and screen space.

I want it to support animated UI, including tweens, bezier curves, springs, and oscillating motion, plus a simple layout system and a tree style hierarchy so UI pieces can be nested and managed cleanly. It should feel useful for things like menu systems, level UI, VFX, and 3D HUDs, not just basic panels.

Please make it easy to drop into a Roblox project, require from a LocalScript, and start building with a clear tutorial and examples. If you need to check current Roblox or Luau docs while building, go ahead. Also include enough documentation so someone lightly technical can understand how to install it and use the main parts without getting lost.
