//! Phase 3 Test Suite: CIDToGIDMap Support for Type0 Fonts
//!
//! This test file implements Test-Driven Development (TDD) for Phase 3 CIDToGIDMap support.
//! Tests are organized into 5 categories following the PDF Spec (ISO 32000-1:2008):
//!
//! - Unit Tests (1-7): CIDToGIDMap parsing
//! - Integration Tests (8-14): DescendantFonts pipeline
//! - Char-to-Unicode Integration (15-18): Full character mapping
//! - Regression Tests (19-21): Phase 2A/2B compatibility
//! - Edge Cases (22-24): Boundary conditions
