//! `atfits-rs` — shared low-level cfitsio helpers for the at*-rs FITS tools
//! (`fitscube-rs`, `convolve-rs`, …).
//!
//! These are the project-agnostic mechanics that every tool needs and that are
//! easy to get subtly wrong against cfitsio:
//!
//! * [`PixelType`] / [`CubeElem`] — precision + monomorphic section I/O.
//! * [`keys`] — update-in-place keyword editing (`ffuky*`, not the duplicating
//!   `ffpky*`) and convenience readers.
//! * [`header`] — [`HeaderGeom`] and WCS [`find_target_axis`] lookup.
//! * [`image`] — image-HDU creation/resize and header-only copying, including
//!   [`create_cube_open`] (the single-open-handle pattern that avoids a doubled
//!   zero-fill pass on close).
//! * [`output_path`] — output-path construction.
//!
//! Domain logic (beams, combine/extract, convolution, spectral specs) stays in
//! the individual crates.
