 * The Accessibility class provides methods for inspecting Chromium's
 * accessibility tree. The accessibility tree is used by assistive technology
 * such as {@link https://en.wikipedia.org/wiki/Screen_reader | screen readers} or
 * {@link https://en.wikipedia.org/wiki/Switch_access | switches}.
 *
 * @remarks
 *
 * Accessibility is a very platform-specific thing. On different platforms,
 * there are different screen readers that might have wildly different output.
 *
 * Blink - Chrome's rendering engine - has a concept of "accessibility tree",
 * which is then translated into different platform-specific APIs. Accessibility
 * namespace gives users access to the Blink Accessibility Tree.
 *
 * Most of the accessibility tree gets filtered out when converting from Blink
 * AX Tree to Platform-specific AX-Tree or by assistive technologies themselves.
 * By default, Puppeteer tries to approximate this filtering, exposing only
 * the "interesting" nodes of the tree.

     * The Mouse class operates in main-frame CSS pixels
     * relative to the top-left corner of the viewport.
     * @remarks
     * Every `page` object has its own Mouse, accessible with [`page.mouse`](#pagemouse).
     *
     * @example
     *
     * ```ts
     * // Using ‘page.mouse’ to trace a 100x100 square.
     * await page.mouse.move(0, 0);
     * await page.mouse.down();
     * await page.mouse.move(0, 100);
     * await page.mouse.move(100, 100);
     * await page.mouse.move(100, 0);
     * await page.mouse.move(0, 0);
     * await page.mouse.up();
     * ```
     *
     * **Note**: The mouse events trigger synthetic `MouseEvent`s.
     * This means that it does not fully replicate the functionality of what a normal user
     * would be able to do with their mouse.
     *
     * For example, dragging and selecting text is not possible using `page.mouse`.
     * Instead, you can use the {@link https://developer.mozilla.org/en-US/docs/Web/API/DocumentOrShadowRoot/getSelection | `DocumentOrShadowRoot.getSelection()`} functionality implemented in the platform.
     *
     * @example
     * For example, if you want to select all content between nodes:
     *
     * ```ts
     * await page.evaluate(
     *   (from, to) => {
     *     const selection = from.getRootNode().getSelection();
     *     const range = document.createRange();
     *     range.setStartBefore(from);
     *     range.setEndAfter(to);
     *     selection.removeAllRanges();
     *     selection.addRange(range);
     *   },
     *   fromJSHandle,
     *   toJSHandle
     * );
     * ```
     *
     * If you then would want to copy-paste your selection, you can use the clipboard api:
     *
     * ```ts
     * // The clipboard api does not allow you to copy, unless the tab is focused.
     * await page.bringToFront();
     * await page.evaluate(() => {
     *   // Copy the selected content to the clipboard
     *   document.execCommand('copy');
     *   // Obtain the content of the clipboard as a string
     *   return navigator.clipboard.readText();
     * });
     * ```
     *
     * **Note**: If you want access to the clipboard API,
     * you have to give it permission to do so:
     *
     * ```ts
     * await browser
     *   .defaultBrowserContext()
     *   .overridePermissions('<your origin>', [
     *     'clipboard-read',
     *     'clipboard-write',

     * :::note
     *
     * One Browser instance might have multiple Page instances.
     *
     * :::
     *
     * @example
     * This example creates a page, navigates it to a URL, and then saves a screenshot:
     *
     * ```ts
     * import puppeteer from 'puppeteer';
     *
     * (async () => {

     *   await browser.close();
     * })();
     * ```
     *
     * The Page class extends from Puppeteer's {@link EventEmitter} class and will
     * emit various events which are documented in the {@link PageEmittedEvents} enum.
     *
     * @example
     * This example logs a message for a single page `load` event:
     *
     * ```ts
     * page.once('load', () => console.log('Page loaded!'));
     * ```
     *
     * To unsubscribe from events use the {@link Page.off} method:
     *
     * ```ts
     * function logRequest(interceptedRequest) {
     *   console.log('A request was made:', interceptedRequest.url());
     * }
     * page.on('request', logRequest);
     * // Sometime later...
     * page.off('request', logRequest);

         * If the function passed to `page.evaluateHandle` returns a Promise, the
         * function will wait for the promise to resolve and return its value.
         *
         * You can pass a string instead of a function (although functions are
         * recommended as they are easier to debug and use with TypeScript):
         *
         * @example
         *

         * ```
         *
         * @example
         * {@link JSHandle} instances can be passed as arguments to the `pageFunction`:
         *
         * ```ts
         * const aHandle = await page.evaluateHandle(() => document.body);
         * const resultHandle = await page.evaluateHandle(
         *   body => body.innerHTML,
         *   aHandle
         * );
         * console.log(await resultHandle.jsonValue());
         * await resultHandle.dispose();
         * ```
         *
         * Most of the time this function returns a {@link JSHandle},
         * but if `pageFunction` returns a reference to an element,
         * you instead get an {@link ElementHandle} back:
         *

         * ```ts
         * const button = await page.evaluateHandle(() =>

         * await button.click();
         * ```
         *
         * The TypeScript definitions assume that `evaluateHandle` returns
         * a `JSHandle`, but if you know it's going to return an
         * `ElementHandle`, pass it as the generic argument:
         *
         * ```ts
         * const button = await page.evaluateHandle<ElementHandle>(...);

         * If you are using TypeScript, you may have to provide an explicit type to the
         * first argument of the `pageFunction`.
         * By default it is typed as `Element[]`, but you may need to provide a more
         * specific sub-type:
         *
         * @example
         *
         * ```ts
         * // if you don't provide HTMLInputElement here, TS will error
         * // as `value` is not on `Element`
         * await page.$$eval('input', (elements: HTMLInputElement[]) => {
         *   return elements.map(e => e.value);
         * });
         * ```
         *
         * The compiler should be able to infer the return type
         * from the `pageFunction` you provide. If it is unable to, you can use the generic
         * type to tell the compiler what return type you expect from `$$eval`:
         *
         * @example
         *
         * ```ts
         * // The compiler can infer the return type in this case, but if it can't
         * // or if you want to be more explicit, provide it as the generic type.
         * const allInputValues = await page.$$eval<string[]>(
         *   'input',
         *   (elements: HTMLInputElement[]) => elements.map(e => e.textContent)
         * );

     * Extends the main {@link Puppeteer} class with Node specific behaviour for
     * fetching and downloading browsers.
     *
     * If you're using Puppeteer in a Node environment, this is the class you'll get
     * when you run `require('puppeteer')` (or the equivalent ES `import`).
     *
     * @remarks
     * The most common method to use is {@link PuppeteerNode.launch | launch}, which
     * is used to launch and connect to a new browser instance.
     *
     * See {@link Puppeteer | the main Puppeteer class} for methods common to all
     * environments, such as {@link Puppeteer.connect}.
     *
     * @example
     * The following is a typical example of using Puppeteer to drive automation:
     *
     * ```ts
     * import puppeteer from 'puppeteer';
     *
     * (async () => {
     *   const browser = await puppeteer.launch();
     *   const page = await browser.newPage();
     *   await page.goto('https://www.google.com');
     *   // other actions...
     *   await browser.close();
     * })();
     * ```
     *
     * Once you have created a `page` you have access to a large API to interact
     * with the page, navigate, or find certain elements in that page.
     * The {@link Page | `page` documentation} lists all the available methods.
