- Assemble AgentCard from AgentStatusBadge, TaskProgressBar, QuickJumpButton - All 6 inputs functional: status, task, progress, sessionKey, channel, lastActivity - Left-border accent matches status color (Active: #38BDF8, Idle: #2DD4BF, Thinking: #A78BFA, Error: #F87171) - Accessibility: role="article" on card, aria-labels on all sections - Uses tactical dark mode CSS variables from CUB-47 - Added @Input() to QuickJumpButton sessionKey for parent binding - JumpClick output forwarded from AgentCard - Build passes, type checking passes
