This plugin fetches and displays the official monetary exchange rates from Cuba's central bank (BCC) on a website. It is designed for site owners, businesses, and individuals in Cuba or dealing with Cuban currency who need to provide visitors with accurate, up-to-date exchange rate information.

• Multiple Display Formats: Choose from a horizontal banner, a compact sidebar widget, or a full-page view with tabs to show all 13 supported currencies.
• Automatic Updates: Rates are refreshed every 30 minutes by consuming the official BCC API, ensuring the data is current without manual intervention.
• Responsive Design: All display formats automatically adjust for desktop, tablet, and mobile screens, including a touch-optimized carousel for smartphones.
• Caching System: An intelligent one-hour cache is used to optimize site performance and reduce server load from API calls.
• Visual Indicators: Rate changes are clearly shown with color-coded variations (green for increases, red for decreases) and tooltips for specific currencies like the Japanese Yen.
