</div>Installation & markup
Include the local stylesheet and script once on the page, then place the component inside a data-xsh-ui root. The example above works without a build system.
<link rel="stylesheet" href="/dist/xshna-ui.css">
<div data-xsh-ui>
<!-- Add the HTML example above -->
</div>
<script defer src="/dist/xshna-ui.js"></script>Component API
Public classes, attributes and hooks used by this example. Keep the xsh- prefix intact.

Accessibility & keyboard
The container is purely structural and does not alter keyboard interaction.
Interaction contract
Behavioral components use the shared delegated runtime; visual-only primitives rely on semantic HTML and CSS. Runtime controls emit bubbling xsh:* CustomEvents; bind application handlers to those events when server persistence, API data or navigation is required.
