/* PurelyTools Robotics — shared styles for every product in this section.
   Self-contained on purpose: the site's header.php loads its CSS by a
   relative path, which 404s from a subdirectory, and this section is a
   separate product line anyway. Add a product by copying eye/index.html
   and adding a card to robotics/index.html. */
