// Component tests for the in-game shell header. The header composes
// the headline strip (`<race> @ <game>, turn N`, falling back to `?`
// while the lobby / report calls are in flight), the view-menu, and
// the account-menu. The tests assert the headline copy, that every
// view-menu entry dispatches `goto` with the right URL, and that the
// Logout entry of the account-menu calls `session.signOut("user")`.
