//! # fast-rich
//!
//! A Rust port of Python's [Rich](https://github.com/Textualize/rich) library
//! for beautiful terminal formatting.
//!
//! ## Features
//!
//! - **Rich text** with colors, styles, and markup
//! - **Tables** with Unicode borders and auto-sizing
//! - **Progress bars** with multiple tasks, spinners, and customizable columns
//! - **Live Display** for flicker-free auto-updating content
//! - **Logging** handler for colorful structured logs
//! - **Tree views** for hierarchical data
//! - **Panels** and **Rules** for visual organization
//! - **Markdown** rendering (optional)
//! - **Syntax highlighting** (optional)
//! - **Pretty tracebacks** for better error display
//!
//! ## Quick Start
//!
//! ### Drop-in Print Replacement
//!
//! ```no_run
//! // Shadow standard print macros with rich versions
//! use fast_rich::{print, println};
//!
//! println!("[bold magenta]Hello, World![/]");
//! println!("Player {} scored [yellow]{}[/] points", "Alice", 100);
//! ```
//!
//! ### Using Console Directly
//!
//! ```no_run
//! use fast_rich::prelude::*;
//!
//! let console = Console::new();
//!
//! // Simple styled output
//! console.print("Hello, [bold magenta]World[/]!");
//!
//! // Tables
//! let mut table = Table::new();
//! table.add_column("Name");
//! table.add_column("Age");
//! table.add_row_strs(&["Alice", "30"]);
//! console.print_renderable(&table);
//! ```
//!
//! ## Markup Syntax
//!
//! The print macros support Rich markup syntax:
//!
//! - `[bold]text[/]` - Bold text
//! - `[red]text[/]` - Colored text
//! - `[bold red on blue]text[/]` - Combined styles
//! - `[[` and `]]` - Escaped brackets (literal `[` and `]`)
//!
//! ## Important: Bracket Handling
//!
//! The markup parser uses a smart heuristic to distinguish between style tags
//! and data brackets:
//!
//! - **Valid Tags**: `[bold]`, `[red]`, `[link=url]` -> Parsed as style
//! - **Data**: `[1, 2, 3]`, `[Unknown]` -> Printed literally as text
//!
//! This means standard debug output usually works out of the box:
//!
//! ```no_run
//! use fast_rich::println;
//!
//! let data = vec![1, 2, 3];
//! println!("Data: {:?}", data); // Prints: Data: [1, 2, 3]
//! ```
//!
//! However, there is a **Known Limitation**: if your data looks exactly like a style tag,
//! the parser will consume it.
//!
//! ```no_run
//! // ⚠️ Unintended Tag Collision
//! let colors = vec!["red", "blue"];
//! // Parser sees "[red", parses it as color tag!
//! // println!("Colors: {:?}", colors);
//! ```
//!
//! For untrusted input or strict correctness, always use the `_raw` macros:
//!
//! ```no_run
//! use fast_rich::println_raw;
//!
//! let colors = vec!["red", "blue"];
//! println_raw!("Colors: {:?}", colors); // ✅ Safe: Prints ["red", "blue"]
//! ```
//!
//! ### Macro Summary
//!
//! | Macro | Markup | Use Case |
//! |-------|--------|----------|
//! | `print!` / `println!` | ✅ Smart | Styled output & most debug data |
//! | `print_raw!` / `println_raw!` | ❌ Skipped | Strict raw data output |
//! | `rprint!` / `rprintln!` | ✅ Smart | Alias (when you need both std and rich) |
//!
//! ### Macro Summary
//!
//! | Macro | Markup | Use Case |
//! |-------|--------|----------|
//! | `print!` / `println!` | ✅ Parsed | Styled output you control |
//! | `print_raw!` / `println_raw!` | ❌ Skipped | Data output, debug values |
//! | `rprint!` / `rprintln!` | ✅ Parsed | Alias (when you need both std and rich) |
