/**
 * Hook that provides access to the current color scheme value.
 *
 * @experimental This hook is experimental and may change in future versions.
 *
 * This hook monitors the color-scheme CSS property on the document's HTML element
 * and returns the current value. It automatically updates when the color scheme changes,
 * either through direct style changes or theme updates stored in localStorage.
 *
 * The hook observes mutations to the HTML element's style attribute to detect
 * color scheme changes and re-renders the component when changes occur.
 *
 * @returns The current color scheme value as a string ('light', 'dark')
