// Local patch: make the platform auth-id requirement for rewards optional.
//
// Adventure Land's tutorial (ureward) and class (creward) handlers require
// player.verified and player.auth_id. auth_id is only populated for Steam/MAS
// accounts; plain web accounts have an empty pid/auth_id and therefore can
// never claim these rewards. On a self-hosted server that requirement is
// usually unnecessary.
//
// options.tutorial_reward_requires_auth_id:
//   true/absent -> upstream behaviour (auth_id required)
//   false       -> verified web accounts may claim the rewards too
//
// The patch is idempotent and fails loudly if the two anchors are gone.
