Build an FAQ with demo video cards in Tailwind CSS: for questions that are easier shown than explained, the answer holds a video card with a thumbnail, play button, duration and a caption, plus the usual text answer underneath for skimmers. Keep videos short (under two minutes), lazy-load the embeds only when the card is opened, and always keep the text answer as the accessible fallback.
