Risk Curves

// `pool` is a loaded Hadron instance; `authority` is the pool authority (see SDK ▸ Quickstart)
// 5 point ask curve with a midprice of 1.00
// Points: Input Amount 0 (base), 1000, 2000, 5000, 10000 units
// Spread of 10, 20, 50, 100, 150 Bps from Mid
// Mixed Interpolation across points
// Initialize risk curve below yellow line

// Same curve as previous example
const askCurveIx = pool.setCurve(authority, {
    side: Side.Ask,
    defaultInterpolation: Interpolation.Linear,
    points: [
        { amountIn: 0n,     priceFactor: 1.0010, interpolation: Interpolation.Step },   // 10bps
