//! # Eoka
//!
//! Stealth browser automation for Rust — a Puppeteer/Playwright alternative that bypasses bot detection.
//!
//! Eoka is a minimal, fast headless Chrome library built from scratch. Unlike Selenium or
//! chromiumoxide, it uses a custom CDP implementation with stealth filtering to avoid detection
//! by Cloudflare, DataDome, PerimeterX, and other anti-bot systems.
//!
//! ## Features
//!
//! - **Stealth by Default** - Binary patching, 15 JS evasions, human-like mouse/typing
//! - **Puppeteer-like API** - `click()`, `type()`, `wait_for()`, `screenshot()`, etc.
//! - **Minimal Dependencies** - ~10 crates total, no chromiumoxide bloat
//! - **AI-Agent Ready** - PageState introspection, element indexing, text extraction
//! - **Fast** - Lazy evasion scripts, mmap patching, stack-allocated paths
//!
//! ## Quick Start
//!
//! ```rust,no_run
//! use eoka::Browser;
//!
//! #[tokio::main]
//! async fn main() -> eoka::Result<()> {
//!     // Launch browser (patches Chrome, applies evasions)
//!     let browser = Browser::launch().await?;
//!
//!     // Create page and navigate
//!     let page = browser.new_page("https://example.com").await?;
//!
//!     // Human-like interactions
//!     page.human_click("#button").await?;
//!     page.human_type("#input", "hello world").await?;
//!
//!     // Screenshot
//!     let png = page.screenshot().await?;
//!     std::fs::write("screenshot.png", png)?;
//!
//!     browser.close().await?;
//!     Ok(())
//! }
//! ```
//!
//! ## Configuration
//!
//! ```rust,no_run
//! use eoka::{Browser, StealthConfig};
//!
//! # #[tokio::main]
//! # async fn main() -> eoka::Result<()> {
//! let config = StealthConfig {
//!     headless: true,
//!     patch_binary: true,
//!     webgl_spoof: true,
//!     canvas_spoof: true,
//!     ..Default::default()
//! };
//!
//! let browser = Browser::launch_with_config(config).await?;
//! # Ok(())
//! # }
//! ```
