engawa-wgpu vs engawa vs engawa-snow

wgpu-backed Dispatcher impl for engawa render graphs. Compiles Material → wgpu::RenderPipeline; walks the compiled graph; dispatches fullscreen-effect passes against any wgpu::TextureView (most commonly a garasu::HeadlessTarget for tests + a winit surface for live).

Engawa (縁側) — typed render-graph IR for pleme-io GPU consumers. Bevy-inspired render-graph design distilled to mado-shaped needs: no ECS, no game loop, no asset pipeline. Pure-data IR + topo sort + cycle detection + integration with garasu's headless GPU primitives.

Flagship snow effect for engawa. Layered parallax snowflakes + cursor-deflection + typing-pulse + accumulation pile, authored in engawa-lisp + WGSL, dispatched through engawa-wgpu. Embeds shader + graph; exposes typed SnowParams uniform and apply() helper for per-frame state push.
