   "Learn more" and "Save for later" used to sit on a row of their own under
   the answers, 46px of the card spent beside the frame the item is in. They
   now ride in the frame's top-left corner, opposite the ✓ / ✗ mark, the way
   the phone has always shown them — with their labels, and bigger, since the
   room the row gave back is theirs to spend. The allowance stays, as the
   frame's own top padding, so the Yes / No word can never rise into them,
   and it is still nothing at all when there is no knowledge bank. */
