/**
 * Hook that syncs state with sessionStorage
 *
 * @template T - The type of the stored value
 * @param key - sessionStorage key
 * @param initialValue - Initial value if key doesn't exist
 * @returns Tuple of [storedValue, setValue]
 *
 * @example
 * ```tsx
 * const Component = () => {
 *   const [theme, setTheme] = useSessionStorage('theme', 'light');
 *   return <div>Theme: {theme}</div>;
 * };
 * ```
 *
 * @remarks
 * SSR-safe: This hook safely handles server-side rendering by checking for window availability.
 * In SSR environments, it returns the initialValue and skips sessionStorage operations.
 * Storage events are also safely handled with proper environment checks.
 * Automatically syncs across tabs/windows via storage events.
