 * KDTechGroup website — Agentic Browser card visual
 *
 * A browser window driven by an agent, on one 12-second loop (CSS only):
 *   1. the request appears in the agent panel
 *   2. the agent's cursor visits three stores in turn, each tab lighting up
 *      and its product card being read
 *   3. the best offer is highlighted, the steps tick off and the agent asks
 *      for approval before it buys anything
 * Reduced motion shows the finished frame: best offer and approval prompt.
