// Vitest coverage for the report view's race-exit-warnings section and
// the personal exit-warning banner. The section lists other races
// within a few turns of inactivity removal and hides entirely when the
// list is empty; the banner shows the local race's own countdown only
// when it is non-zero. Both read the report through the rendered-report
// context, mirroring the other report sections.
