/// Module-level documentation for the `Zjyyer/moonbit-klt-tracker` package.
///
/// The implementation is organized into focused packages for grayscale image
/// buffers, feature detection, KLT estimation, validation, tracking,
/// trajectory formats, and analytics. Applications can depend on the
/// specialized packages under `src` according to the data flow they need.
///
/// The root package intentionally contains documentation only; executable
/// behavior belongs to the focused packages and the `src/cli` command.
