【界面UI】新手引导遮罩：镂空高亮与步骤驱动

---四块遮板拼出镂空窗口
function Guide.mask(hole)
    local m = Guide.node
    local pad = 12
    -- 目标控件四周留 12 像素的呼吸边
    local x, y, w, h = hole.x - pad, hole.y - pad,
        hole.w + pad * 2, hole.h + pad * 2
    Guide.panel(0, 0, m.w, y)                    -- 上
    Guide.panel(0, y + h, m.w, m.h - y - h)      -- 下
    Guide.panel(0, y, x, h)                      -- 左
    Guide.panel(x + w, y, m.w - x - w, h)        -- 右
end

---引导步骤表：目标控件与完成条件
local STEPS = {
    { key = "move",  hint = "点击地面移动",   check = Guide.moved },
    { key = "attack", hint = "点击怪物攻击",  check = Guide.attacked },
    { key = "bag",   hint = "打开背包穿装备", check = Guide.bagOpened },
    { key = "skill", hint = "释放烈火剑法",   check = Guide.skillCast },
}
