//   {{POLICY_RATE_PCT}}   — latest TCMB 1w repo policy rate (e.g. 47.5)
//   {{O_NIGHT_LENDING}}   — overnight lending rate (upper corridor)
//   {{O_NIGHT_BORROWING}} — overnight borrowing rate (lower corridor)
//   {{CPI_YOY_PCT}}       — latest TÜFE annual change
//   {{PPK_DATES_JSON}}    — JSON array of PPK meeting timestamps (ms epoch)
//   {{AS_OF_DATE}}        — YYYY-MM-DD the snapshot was rendered
