WebGPU Memory Model and Alignment

Compute host-side buffer sizes, copy offsets, bytesPerRow, and dynamic bind-group offsets that satisfy WebGPU validation on the first call.

Quick Reference

WebGPU 1.0-stable baseline: Chrome 113+, Safari 26+, Firefox 141+.

WebGPU rejects every misaligned size and offset at validation time. There is NO silent rounding. ALWAYS compute aligned values on the host before the API call.
