 * The VocabCue learning card (markup: includes/vocabcue-card.php), shared by raisul/card-demo and raisul/card-anatomy.
 * VocabCue's own component, not a Raisul Builds interpretation: the study face follows runtime-card.css and the
 * elevated placement (theme visual-vocabulary 3.20.0); the recall, review and done faces follow VocabCue's recall
 * preview (.vv-rp in marketing.css). Values are VocabCue's tokens, copied below. data-step on the card is one of:
 * study, recall, answer, done. Without JS the study face shows; every control that needs JS is rendered [hidden].
