// uses Dictionary<string,object>.TryGetValue, which is case-sensitive — so
// the keys MUST match exactly.
//
// Convention summary (it's mixed):
//   RecNetResult       lowercase           "success", "error"
//   Account            camelCase           "accountId", "displayName", "isJunior"…
//   SelfAccount        camelCase           "email", "birthday", "juniorState"…
//   LoginResponse      snake_case (OAuth)  "access_token", "error_description"…
//   RefreshLoginResp.  lowercase           "token"
//   CachedLogin        camelCase           "platformId", "lastLoginTime"…
//   CreateAccountResp  uses "value" as the wrapper key for the Account dict
//
// NOTE: TreatAsJunior on the C# side maps to JSON key "isJunior" — they
// don't match. Account.Deserialize reads dict["isJunior"], not dict["treatAsJunior"].
