Yawn

Yawn Core is two things: a generic structure-of-arrays arena in a SharedArrayBuffer, and a render-graph worker that turns externally supplied WGSL into an up-front WebGPU loadout.

JSO or FXNode → AST → S-expression → graph worker → WebGPU
                                     ↑
any thread → direct shared row writes ┘

Messages allocate { name, rows, stride, format } arrays and load graphs. Existing render data is changed by writing f32, u32, or i32 rows directly. Allocations are 64-byte aligned, row strides are multiples of 16 bytes, and compatible non-overlapping transient textures share physical allocations.

WGSL, pipelines, glTF import, and conventional mesh/camera/material handles live in addons/; core contains no shader or scene model.
