//! ANSI color codes for terminal output.

//! Four semantic colors with orthogonal dim modifier:
//! - Blue: Definition names, keys, type names
//! - Green: String literals, terminal markers
//! - Dim: Structure, nav, effects, metadata
//! - Reset: Return to default

/// ANSI color palette for CLI output.
