// F8-04b regression spec: paid-tier gate on the `private games`
// sub-panel and the `create new game` button. The gateway is mocked
// at the message-type level (same shape as lobby-flow.spec.ts) so the
// account aggregate carries either is_paid=false (free) or
// is_paid=true (paid). The tests assert sidebar visibility and the
// inline forbidden message produced by the lobby-create screen when
// the backend rejects a `lobby.game.create` from a free-tier caller.
