/**
 * Determines whether animations should be disabled based on user preferences
 * and the current DS CSS custom property for animation duration.
 *
 * This function checks two main conditions:
 * 1. If the user has enabled the "reduce motion" setting in their browser.
 * 2. If the CSS variable `--ds-animation-duration` is set to `'0s'` or `'0ms'`.
 *
 * If the window object is not available (e.g., during server-side rendering),
 * the function will assume that animations should be disabled.
 *
 * @returns {boolean} `true` if animations should be disabled, `false` otherwise.
