已完成「赛事专栏」页面的主体 HTML 与专属 CSS。

**页面结构**（6 个内容区块，信息密度由快扫描过渡到慢浏览）：

1. **专栏刊头与本期索引** — 框景窗口 + 刻度角标，衬线大标题配期次编号；三个等宽大数字（6300 / 1066 / 90）作视觉锚点；右侧窄幅氛围图；下方四则本期导读条目，编号 01–04 分色。
2. **栏目分类标签区** — `data-tabs` 协议承载赛程速报 / 数据观察 / 阵容档案 / 版本笔记四栏，每栏说明定位、更新钟点与关键数字。
3. **最新条目列表** — 12 条，按 `4n+1/4n+4` 占 5 栏、`4n+2/4n+3` 占 7 栏在 12 栅格中错落落位，右列条目下移 46px 形成瀑布节奏；数据观察与阵容档案两条带配图；摘要默认 2 行截断，悬停 / `:focus-within` 展开。
4. **回看集锦索引** — 横向时间轴按比赛日排列，暖橙标记当前轮次，末尾接集锦归档模块入口。
5. **系列专题区** — 横向拖拽容器，卡片左缘露出下一张形成提示，四组长期连载。
6. **订阅与供稿** — 赛季数据包订阅、供稿通道（注明「BET5合作」与响应时长）、纠错入口三栏。

**设计与技术要点**：

- 全部选择器限定在 `.page-news` 作用域，新增变量 `--news-rule`、`--news-rule-soft`、`--news-shadow` 均在页面作用域内定义后使用。
- 复用共享类 `container / section / grid-12 / card / tag / num / btn / media-frame / breadcrumb / timeline / tablist / tabpanel / reveal / eyebrow / section-head` 等，未重定义共享头部与页脚。
- 移动端优先，`700px` 与 `900px` 两个断点；横向滚动容器均设 `min-width: 0` 与 `overflow-x: auto`，避免窄屏横向溢出。
- 4 张图片按 `{zhanqunpic:h:高w:宽}` 协议放置于刊头、数据观察卡片、阵容档案卡片、专题首卡；首屏图不加 lazy，其余带 `loading="lazy" decoding="async"`。
- 所有数字均为可见文本终值，未使用任何等待脚本填充的空属性；交互仅挂在 `data-tabs` 协议上，JavaScript 不执行时标签面板全部平铺可读。
