/**
 * Layout and behaviour regressions are the one class of bug the unit tests
 * cannot see, and this project has shipped several: a chat panel that spilled
 * under the preview, a delete button on top of a timestamp, a focus ring sliced
 * off by the window. All of them are measurable — boxes either overlap or they
 * do not.
 *
 * These boot their own server, agent and database on their own ports. An
 * earlier version pointed at whatever instance happened to be running, which
 * meant the tests wrote throwaway accounts into a real database and stopped
 * working the moment registration was closed on it. A test suite should not be
 * a guest in somebody's live instance.
