Add a file-level comment and in-page requirements section explaining
exactly what is and isn't available for each metric type:
Power (W) -- available on discrete GPU nodes via node-exporter
hwmon collector + i915 driver (no extra config)
Frequency (MHz) -- NOT available; node-exporter --collector.drm is
AMD-only and does not read i915 gt_freq sysfs
Utilization (%) -- NOT available; no standard Prometheus collector
supports i915 engine busy metrics
iGPU nodes -- no metrics at all (iGPU driver has no hwmon)
The in-page MetricRequirements component surfaces this information
directly in the UI so operators know what to expect and why.
