【前端接口】排行榜筛选：按职业与等级的榜单切换

-- 排行榜筛选：本地过滤
local panel = GUI:GetParent("MainTop")
local fullList, curFilter = {}, {job = 0, minLv = 0}
local function renderFiltered()
    local shown = 0
    for i, entry in ipairs(fullList) do
        local jobOk = curFilter.job == 0 or entry.job == curFilter.job
        local lvOk = entry.lv >= curFilter.minLv
        local visible = jobOk and lvOk and shown < 50
        if visible then
            shown = shown + 1
            GUI:setText(rankRows[shown], i .. ". " .. entry.name .. " Lv" .. entry.lv)
        end
    end
    for i = shown + 1, 50 do
        GUI:setText(rankRows[i], "")
    end
end

-- 排行榜筛选：切换交互

        curFilter.job = (curFilter.job == j) and 0 or j
        renderFiltered()
        SL:ShowSystemTips("筛选：" .. JOB_NAMES[curFilter.job + 1])
