// Tradejini is a custom REST broker (NOT Noren) on api.tradejini.com/v2.
// All authenticated calls carry  Authorization: Bearer <api_key>:<access_token>
// where api_key is the app's API secret (BROKER_API_SECRET in OpenAlgo) and
// access_token is the per-session token returned by the individual-token login.
//
// Credential packing:
//   ApiKey    = api_key (app API secret used as the bearer prefix / client id)
//   ApiSecret = password (user account password)
//   AuthCode  = totp     (6-digit time-based OTP)
//
// Auth flow:
//   POST /api-gw/oauth/individual-token-v2  (Bearer <api_key>, form body)
//   body: password=<pwd>&twoFa=<totp>&twoFaTyp=totp
//   → {access_token, token_type:"Bearer", expires_in}
//
// Response envelope for data endpoints: {"s":"ok","d":<payload>}.
