Paint filled-contour bands into the ASCII canvas with an ordered glyph ramp (issue #2077). Each interior character cell is mapped back to a data coordinate (same screen mapping as ascii_fill_quad_primitive), its scalar value is looked up on the grid, and the band index selects a ramp glyph. Cells are written through put_cell at LAYER_DATA so axis spines, ticks, and labels stay reserved.
