Exact-output curve sell. Sizes `avmIn` so that **net** USDC (after the 1.25% sell fee) equals `amount`. This is the **expensive** selector: the user burns whatever AVM it takes.

The quote attaches warning `exact-out-sell-expensive`. Prefer [quoteSellExactAvmIn](/developers/math/quote-sell-exact-avm-in) unless the UI is a "I want $X out" ticket.

## Import

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

## Usage

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

const quote = quoteSellExactReserveOut(snapshot, parseUsdc("10"));

quote.netReserveOutRaw; // the $10 you asked for
quote.avmIn; // tokens burned
quote.grossReserveOutRaw;
quote.residualRaw;
quote.provenance.warnings; // includes exact-out-sell-expensive
```

## Return Value

`SellExactOutQuote`

## Tips

- `prepareSellForNetTarget` is the prepare helper that uses this intent without forcing the expensive selector when an exact-in sell is cheaper.
