 * Base class for ichigo.js-backed Web Components (Light DOM, no Shadow DOM).

 * Mount timing:
 *  - If the component declares no props, the VApplication is mounted synchronously
 *    at the end of connectedCallback (the template is known, no props to wait for).
 *  - If the component declares props, the VApplication is mounted the first time
 *    _setProp() is called after connectedCallback has prepared the DOM. This
 *    guarantees that the parent framework (e.g. ichigo.js VBindDirective) has
 *    already delivered at least one prop value before data() is evaluated.
 *
 * Subclasses must set the static fields _template, _props and _buildOptions before
 * calling customElements.define(). defineComponent() handles this automatically.
