3//! Typed error for every fallible operation in the bake pipeline.
4//!
5//! `BakeError` is the single error type returned by all public fns. It carries
6//! the originating `std::io::Error` for I/O failures and a `String` message for
7//! format violations. Callers can pattern-match without depending on any external
8//! error crate. PROVEN: the graceful-failure discriminator tests verify each arm.
