  ║  HORIZONTAL ACCORDION — USAGE INSTRUCTIONS                  ║
  ╚══════════════════════════════════════════════════════════════╝

  EMBEDDING IN AN IFRAME
  ───────────────────────
    <iframe src="accordion-horizontal.html"
            width="100%"
            height="360"
            frameborder="0"
            allowtransparency="true">
    </iframe>
  Adjust height to suit your content length.

  EDITING CONTENT
  ────────────────
  All content is in the CONTENT section at the top of the
  <script> block near the bottom of this file:

    { heading: 'Your heading', body: 'Your body text.' },

  ADDING OR REMOVING ITEMS
  ──────────────────────────
  Add or remove objects in the items array. The tabs and
  panel rebuild automatically — no HTML changes needed.
  Note: more than 5 items will become cramped on desktop
  and will stack vertically on mobile regardless.

  BEHAVIOUR
  ──────────
  Desktop: tabs sit side by side, content opens in a shared
  panel below the full row.
  Mobile (below 560px): stacks vertically, content opens
  directly below the heading that was clicked.

  CHANGING THE PAGE TITLE
  ────────────────────────
  Edit the <title> tag above.
