this is the part underneath Embellish, it has to be installed for Embellish to work. if youre just here for the mod thats all you need to know.
If youre writing something: it's a small framework for client side effects. one event bus, one particle budget shared by everything so effects cant collectively tank your frames, a surface material table, and hooks for first person hand transforms, third person body animation, ground decals, world space text and the HUD.
Register a feature and you get config persistence, a spot in the settings screen and crash isolation for free. if your feature throws it gets switched off and the client keeps going.
client side only. no packets, no world state. MIT.
