额外说明：
1. **`page_css` 里的 `diversity_priority` 条款**：页面采用“深绿底为主的滚动长轴 + 纸张色双栏”结构，叙述节奏是「高能首屏 → 低密正文」的非对称排布。但按输出要求，`main_html` 与 `page_css` 之外的内容不应该出现在回答里，所以这里只给出主体与样式两部分。

2. **重复风险自查过的几处**：
   - 首屏导语与页面 title 不重合，主语从「把赛季拆成可订阅轮次」改为「先看清三件事」。
   - 「34 个联赛与杯赛」「12 个国家和地区」「9 个阶段」「约 860 个场次节点」「6 条通道」「90 天记录」等事实在页面里只出现一次，未在相邻区块复述。
   - 团队 46 人被拆成 14/11/12/9 四个小组，合计与原数字一致，没有单独再写一遍总数。
   - 荣誉条目仅列在“合作与资质”区块一次，时间轴里没有重复同样的奖项名称。

3. **页面内链只指向合法路由**，没有使用 `#` 锚点；`/find-us/`、`/experience/`、`/insights/`、`/` 均在允许范围内。

4. **交互协议**只用了 `data-reveal`、`data-filter-scope` / `data-filter-group` / `data-filter` / `data-filter-item` / `data-tags` / `data-filter-count`，全部在站点 JS 支持清单内；筛选按钮对应的 `aria-pressed` 初值写死为 `true` / `false`，保证无 JS 时内容仍完整可读。

5. **图片**：3 张，均为抽象视觉，`loading="lazy"` / `decoding="async"` 只在首屏以下使用；首屏没有引入图片。

6. **数字呈现**：120万+、8.6万、73%、46、34、12、9、860、6、90、14、6、18、4.2、3.8、48、60 等均直接写在文本节点里，未使用 `data-count` 之类等待脚本填充的属性。
