  Two tiers: one featured card (total visits) on its own row, then a

  players online. Keeping that second row's own independent flex/grid
  means going from 2 small cards to 3 never leaves an awkward gap or
  forces the featured card to resize — it's just one more same-sized
  cell added to a row that already reflows.
