Module ordering 

Orderings turn Art into a RankMap.

This is the single seam where “reveal the art in a way that depends on the art” lives. Implement Ordering and you control the choreography; the rest of the engine (rendering, easing, diffing) is oblivious to how ranks were chosen.

Structs

Directional

Reveal the art as a clean directional wipe, ranking each cell by its position along one axis. Predictable and intuitive: a tall dragon paints from the top, a wide serpent from the left, and nothing shows until the wipe reaches it. This is the Loader default.

Geodesic

Reveal along the “spine” of the art.

GeodesicReport

Diagnostics describing how well a piece of art suits geodesic reveal.

Scanline

Reveal in reading order: top-to-bottom, left-to-right.

Enums

Direction

The direction a Directional reveal sweeps.

StartHint

Which end of the spine the Geodesic reveal starts at.

Traits

Assigns every ink cell a reveal rank in 0..=1.
