Grafana dashboard for the gpumon_* series from intel-gpu-exporter: current Render/3D busy, GPU power and GT frequency per node as stat tiles, then one time series per engine (Render/3D, Video, VideoEnhance, Blitter) with node as the series, GT frequency, GPU and package power, and memory-controller read/write bandwidth. Node colours are fixed per node across every panel — blue, orange, aqua for k8s-1/2/3 — rather than assigned by series order, so a node keeps its colour whatever the $node filter shows. The trio validates for colour-vision deficiency and normal vision on both Grafana themes (worst all-pairs ΔE 9.4 / 20.9). Reads and writes share one axis and differ by dash, not hue. One axis per panel throughout. gpumon_clients_count is deliberately absent: per-client attribution needs hostPID, which the exporter does not have, so it would read 0 forever and imply an idle GPU.
