                    For <strong>Tabs</strong>, you can style the tab list buttons (direction, active borders, colors) and content layout freely. Just ensure <code>data-tab-group</code> matches between triggers and active panes, and <code>data-tab-target</code> matches the pane ID.
                    For <strong>Accordions</strong>, you can design the headers, chevron SVGs, background panels, and borders. You must maintain the <code>.accordion-item</code>, <code>.accordion-trigger</code>, and <code>.accordion-content</code> class selectors so the script can toggle the collapsed state.
