1//! Shared infrastructure for entrenar CLI tools.
2//!
3//! This crate provides common utilities used across all entrenar sub-crates:
4//! - CLI styling and output formatting
5//! - Error handling with actionable diagnostics
6//! - Table rendering for terminal output
7//! - Progress indicators
8//!
9//! # Toyota Way Principles
10//!
11//! - **Jidoka**: Rich error messages with actionable diagnostics
12//! - **Andon**: Visual problem indication through consistent styling
13//! - **Muda Elimination**: Single source of truth for shared code
