    {name = "月老", x = 120, y = 200, icon = "icon_heart"},
    {name = "铁匠", x = 180, y = 150, icon = "icon_hammer"},

        local btn = GUI:Button_Create(panel, "Marker_" .. m.name,
            m.x, m.y, m.icon)
        GUI:addOnClickEvent(btn, function()
            SL:ShowSystemTips(m.name .. "：" .. (m.desc or ""))
        end)
    end

-- 新手标注：可见性控制
