Hover Reveal Card

Create a card component with a hover reveal effect. The card should show a title and category by default, with a background image or color at partial opacity. On hover, the card expands slightly, the image opacity increases, and additional details (description + link) slide up from the bottom. Use CSS transitions, overflow hidden, and transform. Use Tailwind CSS. The image can be a placeholder gradient or solid color block.
