Detailed Description
MonitorActivity provides an htop-like system resource monitor displaying CPU heatmap, GPU charts, memory/swap chart, filesystem usage, disk I/O, network I/O, and a process list.
All widgets share a unified color scheme based on a two-level mix: final = globalBase * gm + (widgetBase * wm + variation * (1-wm)) * (1-gm) A slider controls the global blend X (gm), blending everything toward the global base color ("matrix green").
