 * Contents
 * 1. Defaults (variables), icon styles
 * 2. List and steps
 * 3. Connector line
 * 4. Icon and number badge
 * 5. Title, text and link
 * 6. Editor hint, reduced motion, responsive
 *
 * Colours read the Design System (--inoforest-color-*) with fallbacks. The defaults sit in :where() blocks (no
 * specificity), so the Style tab controls, which set the same variables on the widget, always win.
 *
 * The Columns control also sets the layout switches (class.php, selectors_dictionary): --ino-sc-v is 1 when the steps
 * stack in one column (vertical connector, 50 px row gap, 460 px centred column, 20 px above and below each step) and
 * 0 otherwise (horizontal connector).
