Draws a 2D saliency heatmap plus a colormap scale bar. Unsigned magnitudes (e.g. Grad-CAM) use Viridis (perceptually uniform, colorblind-safe – hc_information_visualization.md SS4) over [0, max]; signed attributions (any negative value – gradients, IG, LRP, LIME, SHAP) use the blue-white-red DivergingColormap over the symmetric range [-max|v|, +max|v|], so zero is always the neutral midpoint. The choice is ComputeHeatmapColorScale's (plot_data.hpp, unit-tested). Row 0 of the grid is drawn at the top (image convention) with square cells.

- Note
- v1 scope: the standalone heatmap only. Overlaying it atop a source image (the design doc's "overlay heatmap... sufficient figure/ground contrast" guidance) needs an OpenGL texture upload path – deferred to Phase C's TextureCache infrastructure (see plans/okay-we-have-now-buzzing-moth.md), not built here.

Deliberately not unit-tested – see AttributionBarChart's note. All real logic (reshaping) lives in plot_data.hpp's ToSaliencyHeatmap, which is.
