/**
 * What a failing assertion prints — one line of this package's own, over the
 * formatter the engine already ships.
 *
 * This file used to hold a second implementation of `summarizeObservation`,
 * written because the exported one was not called by anything and nobody looked.
 * They rendered the same value into two different strings, which is how a
 * Playwright user and an agent reading the run report end up describing the same
 * observation differently. The merged version lives in
 * [`summarize.ts`](https://github.com/Variance-Authority/variance-authority/blob/main/packages/observe/src/summarize.ts); the seam stays here because
 * *what a failing assertion prints* is this package's contract and
 * [`docket.test.ts`](./docket.test.ts) is where it is held.
 *
 * The message is the product. `1530 pixels differ` is what the incumbent prints
 * and it is unassignable — the only available response is to open the image and
 * look, which is the expensive act this is meant to replace.
 *
 * A snapshot taken inside a case closes with that case and what it had
 * arranged, so a reviewer reads the conditions beside the change.
