//! Fuzz target for the PDF CMap parser.
//!
//! This target tests INV-8 (no panic at public boundary) for the CMap parser.
//! Any panic indicates a CMap parser bug that must be fixed.
//!
//! Note: Full CMap parser is not yet implemented. This target tests the
//! lexer's name and string handling which are foundational to CMap parsing.
