Detailed Description

Backend-neutral waveform thumbnail upload and composition planning helpers.

These primitives describe what a GPU-backed waveform renderer can cache or upload, but they do not own Dawn/Skia/Metal resources. They are safe to use in CPU-only/headless builds and keep WaveformView display-only.
