See [Pure Owl Components](/examples/blocks.html#/docs/guide/owl-components) for how to load `@base/owl` and `dist/baseui.templates.xml`.

## Static component

```base-ui
<div b-ui="questionnaire">Questionnaire</div>
```

## Enhanced usage

Call `BaseUI.mount(element)` or rely on `BaseUI.mountAll()` after the script loads.

## Options and attributes

See `dist/baseui.registry.json` for the supported attribute list.

## Methods

Use the global runtime methods: `BaseUI.mount()`, `BaseUI.mountAll()`, and `BaseUI.destroy()`.

## Events

Interactive components emit documented `baseui:*` events from their root element. Static components do not emit events.

## CSS variables

The component inherits BaseUI semantic tokens such as `--b-surface`, `--b-border`, `--b-primary`, and `--b-radius`.

## Accessibility behavior

The component preserves authored semantic HTML and adds ARIA roles or state attributes where enhancement is required.

## Examples

See `examples/index.html` for a working CDN-style page.

## Browser support

BaseUI targets modern evergreen browsers that support ES modules, CSS variables, and Bootstrap 5.3.

## Test checklist

Verify light and dark themes, keyboard access for focusable controls, disabled or readonly states when applicable, and cleanup through `BaseUI.destroy()`.
