1//! Integer coordinates for discrete grid cells.
2//!
3//! [`Point`] is a zero-based `x`/`y` address whose bounds are defined by a concrete
4//! [`crate::Grid`]; loaders choose the visual origin, not solvers. Prefer
5//! [`condor_core::Point2`] for any-angle or continuous coordinates.

7/// A single grid cell address (`x` column, `y` row), zero-based.
8///
9/// Bounds are relative to a concrete [`crate::Grid`]; construction does not validate.
