//! The crate-wide error type and `Result` alias.

/// The single error type returned across petekIO. Readers validate on load and
/// return a typed `GeoError`, never a panic.

    /// A file's shape/header was not the format the reader expected (an
    /// EarthVision grid handed to the IRAP-points reader), or a recognised but
    /// unsupported variant (wrapped LAS 3.0). Names the detected/declared format
    /// so the caller can route to the right reader instead of getting silent
    /// wrong data.

    /// Two operands had incompatible geometry (e.g. surface ↔ surface math on
    /// differing grids — resample first).

    /// A well-formed request for a capability petekIO does not (yet) support —
    /// e.g. resampling a **rotated** grid geometry, which the shared axis-aligned
    /// resample kernel does not handle. Loud and typed so the caller gets a clear
    /// "not supported" instead of a silent wrong answer.

    #[error("unit error: {0}")]
    Unit(String),
