/* =============================================================
   ARADEL – OPERATIONS STRATEGY CARDS
   File: aradel-operations-strategy-cards/assets/aradel-operations-strategy-cards.css

   Section sits on a light neutral background (#F0F0F0).
   Cards are rich gradient surfaces:
     - Energy Transition: orange → burnt-orange → Sherpa Blue
     - Renewable Energy:  Earth Green → deep green → Sherpa Blue
   CTA circle: tone="white" — white circle on dark gradient.

   Modal body is white. Accent bar at top is skin-coloured.

   Prefix: ar-osc (aradel operations strategy cards).
   No dependency on aradel-related-resources or aradel-prosperity-cards.
