   Bella Ciao · controlV3b — Data cards (replaces agent cards)
   Inherits from controlv3.css (base) + controlv3a.css (SCADA)
   + globe.css (Earth). This file adds:
   • .data-cards grid (replaces .agents)
   • .data-card layout (numbers + mini-viz)
   • mini-visualizations: sparkline, gauge, bars, bidir, stack, zigzag
   • category color stripe (left border, like agent cards)
