/* The four steps of the 90-day plan (ui/shell/ninety-day-plan-steps.js).
 * Pills, buttons, notes and the label/value list come from styles.css; only the layout of the cards lives here.
 * The cards sit below the context bar and the chapter bar, never between them (module-nav-flush).
 *
 * Desktop: four cards in one row; the open detail panel is a second grid row under all four.
 * Mobile: the cards are stacked and the panel follows the card it belongs to.
