/**
 * Playwright global setup (wired via `globalSetup` in playwright.config.ts).
 *
 * Before the test suite runs, open the viewer once against a known study to
 * "warm up" the dev/preview server: trigger the first (slow) Rspack lazy
 * compilation, prime the browser/codec caches, and fetch the study metadata.
 * Without this, the first real spec frequently times out waiting on a cold
 * server compile. This run only loads the page and waits for the layout to
 * render; it makes no assertions.
