Build a pricing tier layout with three cards and a toggle that switches between monthly and yearly billing.
Display three pricing cards (e.g., Basic, Pro, Enterprise) each with features and a price. A toggle lets the user switch between monthly and yearly prices, updating the displayed amounts.
Implement the toggle to update all card prices based on the selected billing period. Highlight a featured card.
Make the layout responsive so cards stack on small screens.
Test that toggling updates prices correctly.
