### 页面结构与内容说明

**首屏区域**采用杂志封面式布局，左侧大标题与导语直接回应"回访用户如何快速判断新旧"，右侧用四组等宽数字呈现更新规模与节奏。背景叠加网格纹理与双色径向光晕，延续竞技深蓝与荧光青的赛事气质。

**四类索引区**将专题、资料库、页面结构、帮助文档做成带编号的分类卡，每张卡对应一个可跳转的锚点，让访客不必通读全表即可直达所关心的条目。置顶条目独立成信号橙描边区块，突出"2026联赛专题新版"这一最大变化。

**更新列表**是本页主体，以杂志目录式连续流呈现12条真实条目。左侧有一条荧光青渐变时间轴，条目节点为菱形。每条包含相对时间、标题、分类标签和一句摘要，细节通过可展开按钮补充。分类标签条吸顶固定，向下滚动时始终可见。

**阶段进展区**用四段进度条呈现2026赛季专题的推进状态，同时标注"已完成""进行中""下一步"三种状态色，与赛季实际节奏对应。

**版本对照表**以新旧路径左右对照的形式呈现五项结构性变化，桌面端为三栏表格，移动端自动折叠为上下排列并加上"旧版/新版"前缀标识。

**回访引导区**使用冰青白浅色块形成页面收束，提示收藏后的固定入口位置，并提供三个明确的下一步动作按钮。
