/**
 * Where a `variancePrecondition` call stands in a Playwright worker.
 *
 * The worker runs one test at a time, and `test.info()` names it in the body
 * and in every hook. Which hook is running Playwright knows and does not
 * publish: `_currentHookType` is read. A recording worker without it fails at
 * setup, in `enterDescribes`; anywhere else a call it cannot tell from a
 * `beforeAll`'s is placed on no case, not guessed to be the body's.
 *
 * Nor does it publish which `describe` declared a running `beforeEach`. The
 * worker runs a test from a clone of the file's suite tree, which its loader
 * keeps per file, and a clone shares its hooks with the tree it was made from.
 * So each `beforeEach`'s depth is read from that tree once per file, before a
 * test's hooks run, keyed by the location object Playwright made when the hook
 * was declared; the running hook is the one whose location object the worker's
 * timeout slot holds.
