Native WebGPU Structured Ash Growth

Interactive Three.js WebGPU/TSL demo for Native WebGPU Structured Ash Growth, with 6 scenarios, 4 mechanisms, and 3 quality tiers and evidence-gated validation.

Evidence status: Accepted runtime evidence is available for the published contract represented by this demo.

Readiness & remaining fixes 1

Declared evidence work remains. Overall implementation status does not establish individual runtime or performance claims.

1. P0Define and measure the target performance contract

   The growth/hero, growth/forest, growth/background tiers have no accepted frame target. Record named device/browser/GPU, viewport, DPR, sustained CPU/GPU/presentation p50 and p95, deadline misses, memory, and settled quality. Submission time is not GPU timing.
