//! # Color Compatibility Module
//!
//! Provides const color aliases as alternatives to inline `Color::Rgb()` values.
//!
//! ## Usage
//!
//! ```rust,ignore
//! use crate::tui::tokens::compat::GREEN_500;
//! let color = GREEN_500;
//!
//! // Or use semantic colors directly:
//! use crate::tui::tokens::colors::ColorPalette;
//! let palette = ColorPalette::tailwind();
//! let color = palette.green_500;
//! ```
