/**
 * Validates that Midnight offers match a named flow's maker side.
 *
 * Use before encoding a side-specific Midnight action: make-lend and
 * take-borrow consume buy offers (`expectedBuy: true`), while make-borrow and
 * take-lend consume sell offers (`expectedBuy: false`).
 *
 * @param offers - Offers to validate.
 * @param expectedBuy - Expected maker side for every offer.
 * @returns Nothing after every offer has the expected maker side.
 * @throws {MidnightOfferSideMismatchError} when any offer side differs from `expectedBuy`.
 * @example
 * ```ts
 * import { validateOfferSides } from "@morpho-org/morpho-sdk";
 *
 * validateOfferSides([{ buy: false }, { buy: false }], false);
 * ```
