HTML
<div class="xsh-row">
<button class="xsh-button xsh-button--secondary" data-xsh-toast="success" data-xsh-title="Saved successfully" data-xsh-message="All changes have been saved.">Success toast</button>
<button class="xsh-button xsh-button--secondary" data-xsh-toast="warning" data-xsh-title="Check required" data-xsh-message="One field needs your attention.">Warning toast</button>
<button class="xsh-button xsh-button--secondary" data-xsh-toast="danger" data-xsh-title="Action failed" data-xsh-message="Please try again.">Error toast</button>
</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
Toasts use status or alert semantics and have an explicit dismiss control. Timers pause while hovered or focused.
Implementation note. Do not use a disappearing toast as the sole channel for critical information.
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.
