Previously, colors were generated in HeatmapCollector based on intensity, and the same colors were used for both light and dark themes. As a result, the displayed colors didn’t always match the color legend for the selected theme. To fix this, we now compute only the intensity for both self and total samples in HeatmapCollector. The actual color is chosen later based on that intensity and the active theme, ensuring the lines correctly follow the theme-specific color legend.
The _color_cache itself is no longer needed because colors are no longer generated in HeatmapCollector.
