     inside needs, and the cards end up as long horizontal strips
     with empty space trailing off to the right. Capping at 720px
     gives ~240px per tile, similar to Amazon's hub density, and

   wrapper in the JS). Two overrides relative to .card:
   1. Padding: the JS doesn't wrap the tile content in .card-body,
      so without explicit padding the text sits flush against the
      1px border and feels cramped. Match .card-body's 16px.
   2. overflow: visible: .card's default `overflow: hidden` clips
      content against the 20px border-radius, which truncates the
      top/bottom of the badge pill at the right edge of the tile
      (the "letters being cut off" the user reported). Hub tiles
      have no image to round-corner, so the clip serves no purpose
      here. The hover-lift still works — the visible 2px shift
      against the page background is barely perceptible. */
