+/**
+ * QuizzesCTA — the way into /quizzes, in two shapes:
+ *
+ *   - "tile":   a card that leads the search page's "Start here" row.
+ *   - "banner": a full-width row for the homepage, under sādhana / vāṇī.
+ *
+ * Renders nothing until there is at least one published quiz; with
+ * `pendingOnly` it also hides once every quiz has been finished, so the
+ * homepage only nudges when there's something left to do.
