   Sectors & Core Capabilities
   Cards read as equipment nameplates — the rated-capacity plate bolted to
   transformers/switchgear stating class and duty. Angled corner via
   clip-path keeps them geometric and distinct from the rounded pillar
   cards above, while staying in the same maroon/gold system.
