13//! The single crate-level error type. It replaces what used to be four
14//! separate per-module enums (`canvas`, `font`, `component`, `encoder`), so
15//! callers match one type and `?` composes across the whole crate. Each of
16//! those modules now re-exports `Error`/`Result` from here, keeping the old
17//! `canvas::Error`, `font::Error`, … paths valid.
