/* --- content images ---
   The reset already sets `max-width: 100%; height: auto` so the browser
   scales images down proportionally to fit the column without stretching.
   These rules add the visual treatment: centered placement, vertical
   breathing room, and rounded corners. We deliberately don't force a
   width — small icons or graphics shouldn't be upscaled and blurred. */
