 > **Frontend validation:** the user-entered `amount` must be a multiple of `loan_multiplier` (e.g. if `100000`, only values like `100000`, `200000`, `1500000`, … are accepted).
 
+> **`simulation` field:** the `/form` response now also includes a pre-fetched list of simulations (same shape as `usecase.LoaTermResponse.simulation`). The simulations are calculated using the card's `maximum_loan` so the frontend can render a sample of available tenors before the user finishes entering an amount. The full per-amount simulation is still returned by `/term`.
