//! Shared float-space primitives for graph-family geometry.
//!
//! These types are used across core geometry contracts, grid replay metadata,
//! and routing helpers. They live outside `geometry` so consumers can depend
//! on float-space points and rectangles without pulling in higher-level graph
//! solve contracts.

/// Float-precision rectangle (layout coordinate space).
