Contract
- customElements.define registers custom element lifecycle callbacks (connectedCallback, disconnectedCallback, attributeChangedCallback) that execute synchronously upon DOM tree mutation and observed attribute modification.
- Defining a custom element automatically upgrades matching pre-existing elements in the active DOM tree, replacing the node and triggering connectedCallback.
- attachShadow creates open or closed shadow roots where mode open exposes element.shadowRoot and mode closed keeps element.shadowRoot as null.
- Composed events dispatched inside a shadow root bubble across the shadow boundary through light DOM ancestors to Window, populating composedPath with the shadow root, host, and document nodes.
