DCP 2.1.1: Singlecol Shader — Two-Color Blending

dcp_singlecol.gdshader now supports smooth runtime blending between two palette cells.

The cell selection is split into two pairs — cell_a_x/cell_a_y and cell_b_x/cell_b_y — with a mix_a_b float uniform (0.0 = Color A, 1.0 = Color B). Drive it from an AnimationPlayer, a tween, or script logic to crossfade between any two palette colors on a mesh without touching its UVs.

quadrant and emission_strip remain shared: PBR values (roughness, metalness, emission) are defined by the quadrant, not the individual cell, and are consistent across both colors.

Regenerate the shader export from the DCP Configure dialog to get the updated template.
