Use this before writing markup for a component to see how it is actually used in Angular, React, Vue or vanilla JavaScript — the template, the component class and the styles that belong together. Call it without an `example` first to see which examples the component offers. Returns the examples of the component with the frameworks each provides, or, when an `example` is given, its code per framework as fenced code blocks — one section per framework, and one block per file where an example spans several files. Do not use this for the component's API reference: its properties, events, methods, CSS shadow parts, CSS custom properties and slots are on the documentation page, which `get_doc_page` returns.",
