   PDP Highlights — Dashboard (revamped)
   Self-contained styles. Reuses the brand tokens / topbar / form
   controls from styles.css; everything metric-related is scoped
   under the `db-` namespace so it never collides with other pages.
   Layout uses CSS multi-column masonry: each card is only as tall
   as its own content — cards are never stretched to match a row.
