//! # Modules
//!
//! - [`optics`] — plate scale and field-of-view geometry from focal length,
//!   pixel size (x/y), binning (x/y), and sensor dimensions — or a directly
//!   supplied pixel scale / field of view — plus the search-radius policies.
//! - [`matcher`] — the `SkyObject` input trait, match constraints (radius,
//!   rectangular field of view, nearest-N), and deterministic ranking.
//! - [`guide`] — a task-oriented walkthrough, from implementing `SkyObject`
//!   through repeated queries with `Matcher`.
