This is where the opening paragraph goes — the hook that pulls someone in, whether that's a strong opinion, a surprising detail about a case, or a pop-culture reference that sets up the rest of the piece.
Body copy can run as long as it needs to. Paragraphs stay readable at a comfortable measure regardless of viewport, matching the same editorial type scale used across the case studies, so a post styled this way will always feel like part of the same site rather than a bolted-on section.
Additional images inside a post can just be dropped in as regular content images
between paragraphs — no special markup needed beyond a standard <figure>.
