🔁 Steps to Reproduce

1. Navigate to the swap interface for a pool that utilizes a hook for its fees.
2. Example Pool: https://app.uniswap.org/explore/tokens/ethereum/0xd0cC2b0eFb168bFe1f94a948D8df70FA10257196?inputCurrency=NATIVE
3. Enter any amount for the input token (e.g., 0.01 ETH).

---

✅ Expected Behavior

The price impact should dynamically reflect the actual slippage based on the input amount relative to the pool's liquidity. For a small trade, this value should be low.

---

❌ Actual Behavior

The UI displays a static, high price impact (10% in the provided example) regardless of the input trade size. This suggests the fee from the hook might be being misinterpreted as price impact.

⚠️ Please redact or avoid sharing sensitive data such as private keys, seed phrases, or personally identifying info.

Start by reproducing the issue in the swap interface using the linked example pool and a small ETH amount. Trace how the web app calculates and displays price impact for pools with hook-based fees; done means the displayed impact changes with trade size and no longer shows a static 10% for the example.
