The "Living Sparklines" pulse animation in the DevIndex grid lacks contrast in the light theme. The white-based radiant aura works well for dark themes but washes out on light backgrounds, making the pulse look like a fast-moving dot and the peak effect barely noticeable.

We will add a pulseRGB configuration to the static colors map for both themes, using 255, 255, 255 for dark mode and 62, 99, 221 (primary blue) for light mode, and update the rendering logic to utilize this color for the glow and peak flash effects.
