   IRONBEASTS - CATEGORY PHOTO CARDS  (cat-cards.css)
   The "Shop by Category" card: a 4:5 photo with the category's name over a
   shaded foot. On the homepage it sits on the scrolling track (home.css holds
   the track); on the 404 page in a plain grid (error.css). Loaded only on
   those two, never site-wide.
