【界面UI】BUFF 图标栏：增益排列与剩余时间

---BUFF 栏：图标按类型分组排列
BuffBar.icons = {}

function BuffBar.sync(list)
    -- list: 服务器推送的增益数组
    BuffBar.clear()
    local order = { buff = 1, debuff = 2 }
    table.sort(list, function(a, b)
        if order[a.kind] ~= order[b.kind] then
            return order[a.kind] < order[b.kind]
        end
        return a.expireAt > b.expireAt
    end)
    for i, b in ipairs(list) do
        if i <= 12 then
            BuffBar.place(b, i)
        end
    end
end

---剩余时间：秒数的颜色分级
SL:Schedule(0.5, function()
    for _, icon in pairs(BuffBar.icons) do
        local left = icon.expireAt - os.time()
        if left <= 0 then
            BuffBar.remove(icon)
        else
            local txt = SL:SecondToHMS(left)
            GUI:Text_setString(icon.label, txt)
            local color = left <= 5 and "#FF4444"
                or (left <= 15 and "#FFAA00" or "#FFFFFF")
            GUI:Text_setString(icon.label, txt)
            BuffBar.color(icon, color)
        end
    end
end)
