 * SSO Cookie Utilities
 *
 * Provides a shared cookie mechanism for cross-domain SSO.
 * In local dev, all products share *.local.burdenoff.com so a cookie works.
 * In production, the Storage Access API handles cross-domain storage;
 * the cookie serves as a fast-path signal that a session exists.
