This plugin detects whether a visitor is logged in by reading a browser cookie, enabling dynamic user interface adjustments on heavily cached websites. It is designed for developers building custom themes or applications where full page caching is used but user-specific content or actions need to be managed.

• Visibility Control: Adds CSS classes (ct-logged-in or ct-not-logged-in) to the site's HTML element, allowing you to show or hide specific page elements based on login status using simple CSS rules.
• JavaScript Utilities: Provides a global CookieTasting object with methods like userName() to get the current user's name and lastUpdated() to check the timestamp of the last login verification.
• Event-Driven Updates: Emits a custom JavaScript event (cookie.tasting) when the login status is periodically checked, allowing frameworks like React or jQuery to update the UI state in real time.
• Secure Action Verification: Includes a testBefore() method to perform a fresh credential check via a promise before executing sensitive actions (like loading premium content), helping prevent unauthorized access on cached pages.
• User Identification: Assigns a unique UUID to both logged-in and anonymous users, which can be utilized for analytics tracking or as a consistent user identifier across sessions.
