/**
 * Initializes and returns a constant value that persists across component renders.
 *
 * This is useful for creating object instances, arrays, or other values that should only be
 * created once per component instance and remain stable.
 *
 * It uses a `useRef` internally to store the value.
 *
 * @template T The type of the constant value.
 * @param {Initializer<T> | T} initializer A function that returns the initial value, or the initial value itself.
 *                                       If a function is provided, it's guaranteed to be called only once.
 * @returns {T} The constant value.
