Removes `collateralRemoved` AVM from the position via a curve sell, then applies `debtDecrease` as a repay from the sell proceeds. Any leftover net USDC is `netReserveToUserRaw`.

`priceImpact` is the sell impact. You cannot remove more AVM than the position holds.

## Import

```ts
import { quoteShrinkExactAvmIn } from "@repo/contract-client/math";
```

## Usage

```ts
import { parseAvm, parseUsdc } from "@repo/contract-client";
import { quoteShrinkExactAvmIn } from "@repo/contract-client/math";

const quote = quoteShrinkExactAvmIn(snapshot, position, {
  collateralRemoved: parseAvm("100"),
  debtDecrease: parseUsdc("5"),
});

quote.collateralRemoved;
quote.debtDecreaseRaw;
quote.netReserveToUserRaw;
quote.position;
quote.priceImpact.totalPriceImpactWad;
```

If `debtDecrease` exceeds current debt, it is clamped to `position.debtRaw`.

## Return Value

`ShrinkQuote` with `kind: 'shrinkExactAvmIn'`

| Field                 | Meaning                                  |
| --------------------- | ---------------------------------------- |
| `collateralRemoved`   | AVM sold                                 |
| `debtDecreaseRaw`     | Debt actually repaid                     |
| `netReserveToUserRaw` | Sell proceeds minus repay (floored at 0) |
| `position`            | After both legs                          |
| `priceImpact`         | From the sell                            |

## Parameters

  collateralRemoved: parseAvm("100"),

## Error

`InsufficientFreeCollateral` if `collateralRemoved > position.collateralAvm`. Nested sell errors if the curve payout is too small.
