**改写说明**：
- **品牌文化定位与信息架构**：按“我们做什么—内容体系—版本归档—数据核对—合作生态—发展历程”的客户决策路径重组页面，完整覆盖六个 required_sections 的信息目标，并把“九个赛季”“32 人团队 11 人核对”“9 家媒体 5 家数据服务商”等经营数据融入业务叙述。
- **视觉与交互设计**：采用纵向赛季时间轴加左右交替图文，中段插入团队分工横条打断节奏；首屏超大标题配赛季刻度竖栏，数据带展示五项运营规模，色彩仅用青、品红、黄三点缀，符合深空黑主调的场馆战术板气质。
- **文案自然化处理**：所有章节标题与正文重新撰写，未复用 required_sections、site_strategy 或 known_facts 的句式，避免“动线”“矩阵”“口径”等内部术语，联系信息仅保留在页脚（由外壳注入），本页通过指向联系合作页的链接代替。
