1//! Crate-local error type used by `oxideav-tiff`'s standalone
2//! (no `oxideav-core`) public API.
3//!
4//! Defined as a small std-only enum so the crate can be built with the
5//! default `registry` feature off — i.e. without depending on
6//! `oxideav-core` at all. When the `registry` feature is on (the
7//! default) a `From<TiffError> for oxideav_core::Error` impl is enabled
8//! in [`crate::registry`] so the `Decoder` trait surface still
9//! interoperates cleanly.
10//!
11//! The variants mirror the subset of `oxideav_core::Error` the TIFF
12//! decoder pipeline actually produces.
