Module geometry 

Geometry stage: composited stored samples -> oriented canvas region. This does not establish target color, perform blending or resize for display.

Structs

ProjectionSource

Immediate input coordinates retained as provenance, not current pixel facts.

Enums

Refusal

Required geometry or interpretation could not be established.

Functions

project

Geometric projection only. All mapped planes are validated before payload admission. Cropping is in oriented canvas coordinates; unsupported raw views, placement, component codes or unaligned auxiliary grids refuse explicitly. Source decoding/composition has already happened and retains its own costs. Auxiliary registration must be explicitly established by its adapter; dimensions alone do not authorize projection. Other grids require their own geometry representation and resampling mechanism before they can be offered. None adds no per-call control; geometry and storage checks still apply.
