- icons/gen writes to the current directory so `go generate ./internal/master/web/icons` works (output verified byte-identical) - share the registry-host check as imageref.IsRegistryHost (with test) - agents fragment refreshes the "N machines" header count out of band - ignore the saved machine filter at <=760px where the machine list is hidden - aria-current on the active machine filter link, aria-pressed on theme toggle - CLAUDE.md: icons package, SSE ping event, swarm_cluster_id Claude-Session: https://claude.ai/code/session_01GAZsp3P7Qto6JnhipxWUJQ
