 * Modifications (c) YANDEX LLC / gravity-ui contributors:
 *  - ported to TypeScript and moved out of the Playwright process into this package;
 *  - ZIP access reimplemented on top of `node:zlib` (see `./zip`);
 *  - `harFile` exposed so that `addHarOpenTransform` can mutate it before any lookup.
