/**
 * WORKFLOWS COMPLETS & EMPTY STATES
 *
 * Imported from `@playwright/test` rather than `@chromatic-com/
 * playwright` because the latter installs an automatic post-test
 * `takeSnapshot` that races the in-flight /login navigation at the
 * end of the logout step, producing "Execution context was destroyed"
 * on every run. The test asserts behavior, not visuals — chromatic
 * snapshots add no value here. Visual tests live in dedicated
 * spec files that use the chromatic wrapper deliberately.
