 * Demo/video placeholder styling for category pages
 *
 * Each category page can include a `.category__demo` wrapper
 * containing an `<img>` element. This ensures the image scales
 * nicely within the card layout, has rounded corners and a subtle
 * shadow, and is spaced evenly from surrounding content. The
 * container applies top and bottom margins to separate the demo
 * from the description and example sections.
