//! # Page Management and Interaction
//!
//! The `Page` type represents a browser tab and provides methods for navigation,
//! content interaction, and capturing screenshots or PDFs.
//!
//! ## Features
//!
//! - **Navigation**: Navigate to URLs, go back/forward, reload
//! - **Element Interaction**: Locate and interact with elements via [`Locator`]
//! - **JavaScript Evaluation**: Execute JavaScript in the page context
//! - **Screenshots**: Capture viewport or full page screenshots
//! - **PDF Generation**: Generate PDFs from page content
//! - **Input Devices**: Control keyboard, mouse, and touchscreen
//! - **Event Handling**: Handle dialogs, downloads, console messages
//! - **Network Interception**: Route, modify, and mock network requests
//! - **Clock Mocking**: Control time in the page with [`Clock`]
//! - **Frames**: Access and interact with iframes via [`Frame`] and [`FrameLocator`]
//! - **Video Recording**: Record page interactions
//!
//! ## Quick Start
//!
//! ```no_run
//! use viewpoint_core::{Browser, DocumentLoadState};
//! use std::time::Duration;
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! let browser = Browser::launch().headless(true).launch().await?;
//! let context = browser.new_context().await?;
//! let page = context.new_page().await?;
//!
//! // Navigate to a URL
//! page.goto("https://example.com")
//!     .wait_until(DocumentLoadState::DomContentLoaded)
//!     .goto()
//!     .await?;
//!
//! // Get page title
//! let title = page.title().await?;
//! println!("Page title: {}", title);
//!
//! // Get current URL
//! let url = page.url().await?;
//! println!("Current URL: {}", url);
//! # Ok(())
//! # }
//! ```
//!
//! ## Element Interaction with Locators
//!
//! ```no_run
//! use viewpoint_core::{Browser, AriaRole};
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! # let browser = Browser::launch().headless(true).launch().await?;
//! # let context = browser.new_context().await?;
//! # let page = context.new_page().await?;
//! // Click a button
//! page.locator("button#submit").click().await?;
//!
//! // Fill an input
//! page.locator("input[name='email']").fill("user@example.com").await?;
//!
//! // Get text content
//! let text = page.locator("h1").text_content().await?;
//!
//! // Use semantic locators
//! page.get_by_role(AriaRole::Button)
//!     .with_name("Submit")
//!     .build()
//!     .click()
//!     .await?;
//!
//! page.get_by_label("Username").fill("john").await?;
//! page.get_by_placeholder("Search...").fill("query").await?;
//! page.get_by_test_id("submit-btn").click().await?;
//! # Ok(())
//! # }
//! ```
//!
//! ## Screenshots and PDF
//!
//! ```no_run
//! use viewpoint_core::Browser;
//! use viewpoint_core::page::PaperFormat;
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! # let browser = Browser::launch().headless(true).launch().await?;
//! # let context = browser.new_context().await?;
//! # let page = context.new_page().await?;
//! // Viewport screenshot
//! page.screenshot()
//!     .path("screenshot.png")
//!     .capture()
//!     .await?;
//!
//! // Full page screenshot
//! page.screenshot()
//!     .full_page(true)
//!     .path("full-page.png")
//!     .capture()
//!     .await?;
//!
//! // Generate PDF
//! page.pdf()
//!     .format(PaperFormat::A4)
//!     .path("document.pdf")
//!     .generate()
//!     .await?;
//! # Ok(())
//! # }
//! ```
//!
//! ## Input Devices
//!
//! ```ignore
//! use viewpoint_core::Browser;
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! # let browser = Browser::launch().headless(true).launch().await?;
//! # let context = browser.new_context().await?;
//! # let page = context.new_page().await?;
//! // Keyboard
//! page.keyboard().press("Tab").await?;
//! page.keyboard().type_text("Hello World").await?;
//! page.keyboard().press("Control+a").await?;
//!
//! // Mouse
//! page.mouse().click(100.0, 200.0).await?;
//! page.mouse().move_to(300.0, 400.0).await?;
//!
//! // Touchscreen
//! page.touchscreen().tap(100.0, 200.0).await?;
//! # Ok(())
//! # }
//! ```
//!
//! ## Event Handling
//!
//! ```ignore
//! use viewpoint_core::Browser;
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! # let browser = Browser::launch().headless(true).launch().await?;
//! # let context = browser.new_context().await?;
//! # let page = context.new_page().await?;
//! // Handle dialogs
//! page.on_dialog(|dialog| async move {
//!     println!("Dialog: {}", dialog.message());
//!     dialog.accept(None).await
//! }).await;
//!
//! // Handle downloads
//! page.on_download(|download| async move {
//!     download.save_as("file.zip").await
//! }).await;
//!
//! // Handle console messages
//! page.on_console(|msg| async move {
//!     println!("[{}] {}", msg.message_type(), msg.text());
//!     Ok(())
//! }).await;
//! # Ok(())
//! # }
//! ```
//!
//! ## Frames
//!
//! ```ignore
//! use viewpoint_core::Browser;
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! # let browser = Browser::launch().headless(true).launch().await?;
//! # let context = browser.new_context().await?;
//! # let page = context.new_page().await?;
//! // Access iframe by selector
//! let frame = page.frame_locator("iframe#content");
//! frame.locator("button").click().await?;
//!
//! // Access iframe by name
//! let frame = page.frame("content-frame").await;
//! if let Some(f) = frame {
//!     f.locator("input").fill("text").await?;
//! }
//! # Ok(())
//! # }
//! ```
//!
//! ## Clock Mocking
//!
//! ```ignore
//! use viewpoint_core::Browser;
//!
//! # async fn example() -> Result<(), viewpoint_core::CoreError> {
//! # let browser = Browser::launch().headless(true).launch().await?;
//! # let context = browser.new_context().await?;
//! # let page = context.new_page().await?;
//! // Install clock mocking
//! page.clock().install().await?;
//!
//! // Set to specific time
//! page.clock().set_fixed_time("2024-01-01T12:00:00Z").await?;
//!
//! // Advance time
//! page.clock().run_for(60000).await?; // 60 seconds
//! # Ok(())
//! # }
//! ```
