/**
 * CCI Feature Bar
 *
 * A row of short, gold gradient uppercase labels (course highlights such as
 * "Self-paced", "Online format", …) separated by thin blue divider lines that
 * fade at their ends. Responsive:
 *  - Desktop / Tablet (>=768px): a single row, a vertical divider between each
 *    label. Labels share the width equally and wrap their text as needed.
 *  - Mobile (<=767px): a 3-up grid — vertical dividers between the labels in a
 *    row and a full-width horizontal divider between rows.
 *
 * Dividers are drawn with CSS gradients on item pseudo-elements positioned in
 * the gaps, so the widget works for any number of labels. Defaults match the
 * Figma design.
