              Real work is messy, distributed, and embedded in internal systems. Cloud AI often 
              cannot operate there. Useful AI runs inside the environment and supports human 
              decision-making — not abstract it away. We sit with the operators, map the steps, 
              and build a system that mirrors what actually happens.
