Interactive Three.js WebGPU/TSL demo for WebGPU Directional Shadow Architecture Bench, with 4 scenarios, 4 mechanisms, and 1 quality tier and evidence-gated…

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

Readiness & remaining fixes 2

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

1. P0Define and measure the target performance contract

   The high tier 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.
