/**
 * Screenshot spec for structured agent provider error states (PR #1653).
 *
 * Exercises the two visible surfaces where friendly error copy appears:
 *   - Agent card avatar badge (CircleAlert icon + tooltip) for stopped agents
 *     with a lastError / lastErrorCode.
 *
 * ManagedAgentRow (StatusBlock text) is also exercised here even though it is
 * not yet wired into a reachable route in the main app — it will be connected
 * in the follow-up config-bridge PR.  We render it in isolation by navigating
 * to the agents view and letting the mock bridge expose the row through the
 * unified section once that wiring lands; for now we capture the card badges
 * which ARE reachable in the current build.
