Explained in The .drft container.

const ATTR_LAYERS: number
import { ATTR_LAYERS } from '@driftengine/drft';

In depth

Next free bit, appended last, for the reason grain gives at length: a 1.19 reader meets the arrays it knows where it expects them, stops before this one, and draws every face at layer 0 — the first image of the array, which is what a reader that has never heard of layers should produce.
