The SIO clock went from nearly idle (0.014%) to fully active (100%), and video subsystem power rails TVVi and TVEi surged +349% (0.50W → 2.26W) and +306% (0.23W → 0.93W) respectively. CPU workload is broadly elevated: WindowServer pcpu-instructions +627%, WebKit.GPU pcpu-instructions +336%, WebKit.WebContent cputime +95%, WebKit.Networking cputime +72%.
