/* IELTS Listening lab (/study/ielts/listening-lab). Square like the rest of Study; uses the IELTS roadmap tokens.
 * Word marks never rely on colour alone: wrong words are struck through and followed by the right word, missed
 * words sit in a dashed box, extra words are struck through, and the legend says which is which. */
