/**
 * Calculate the expected outcome based on current price and strikes
 *
 * For High Pool:
 * - Outcome 0: price < strikes[0]
 * - Outcome 1: price >= strikes[0] AND price < strikes[1]
 * - Outcome 2: price >= strikes[1] AND price < strikes[2]
 * - Outcome 3: price >= strikes[2]
 *
 * For Low Pool:
 * - Strikes are in DESCENDING order: [strike0=$160, strike1=$150, strike2=$140]
 * - Outcome 0: price >= strikes[0] (price >= $160, no strikes hit)
 * - Outcome 1: price < strikes[0] AND price >= strikes[1] (below $160, above $150)
 * - Outcome 2: price < strikes[1] AND price >= strikes[2] (below $150, above $140)
 * - Outcome 3: price < strikes[2] (below $140, all strikes hit)
 *
 * CRITICAL: Low Pool strikes must be checked from lowest to highest (s2 → s1 → s0)
 * using independent if statements to allow cumulative outcome assignment.
 *
 * @param priceInCents - Current price in cents
 * @param strikes - Strike prices in cents [strike0, strike1, strike2]
 * @returns Outcome for both High and Low pools
 *
 * @example
 * ```typescript
 * // High Pool strikes: [140, 150, 160] (ascending)
 * const result = calculateOutcome(15500, [14000, 15000, 16000]);
 * // result.highOutcome = 2 (price >= 150 but < 160)
 *
 * // Low Pool strikes: [160, 150, 140] (descending)
 * const result = calculateOutcome(15500, [16000, 15000, 14000]);
 * // result.lowOutcome = 1 (price < 160 but >= 150)
 * ```
