/* Text-only card. Posts without a featured photograph would otherwise render an empty
   16:9 frame, which reads as a broken image. This fills the same slot with a navy
   plate so the grid rhythm holds and the card looks deliberate. The label is set in
   CSS content on purpose: it is decorative, and the real category is already in
   .eyebrow--card just below, so this stays out of the accessibility tree. */
