/* The strategy quiz, /quiz/ (templates/quiz.mjs, assets/js/quiz.js): a head on the stars like the terms' pages, then one
   column of 760 px at most with the form on a panel of the second space tone and, under it, the result on the same
   panel. Cream for everything that is chosen or next; gold only on "See <Name>", which leads to a strategy's buy box,
   as Subscribe does everywhere. Without JavaScript every question shows, one under the other, and the six cards under
   them; with it (html.quiz-js before the first paint, html.quiz-ready once quiz.js runs) one question at a time and
   then the result. The question and the result slide in only while the motion setting is on. */
