Gotchas

• Custom-tier organizations have no monthly spend cap; limits are arranged with the account team.
• The 429 looks like a rate-limit error: check error.details.error_code to tell them apart.
• Docs say the limits are intended to reduce unintentional overspend; they don't promise the charge will stop at exactly that amount.
