//! Fuzz target for the PDF stream decoder.
//!
//! This target tests INV-8 (no panic at public boundary) for the stream decoder.
//! Any panic indicates a stream decoder bug that must be fixed.
//!
//! This also tests EC-10 (decompression bomb) - the 512 MB limit must hold
//! under random predictor inputs.
