等等，我在输出末尾写了 `</main>`，这不对。主 HTML 应以 `</main>` 结束，之后不应再有别的。让我只输出标记及其内容。

而且我犯了一个错误——PAGE_CSS 块里也包含了 `</main>`。让我修正。

实际上，重新读一遍：main_html 应以 `</main>` 结束。然后 PAGE_CSS 标记应包含 CSS。我意外把 `</main>` 放进了 CSS 里。

让我只输出标记及其内容。

        <p>
          做补时数据的念头来自一个很具体的场景：一名球迷想知道球队在主场的平均补时是不是真的比别人长，翻遍赛后统计却找不到现成的答案。比分有人记，射门有人记，偏偏补时这种直接决定比赛节奏的数据没人认真收集。
        </p>
        <p>
          我们因此从 2018 赛季开始逐场记录补时时长。它看起来只是一个数字，但拉开七个赛季后，它会变成一种阅读比赛的方式——哪支球队在补时阶段被追平、哪个场馆的补时明显偏长、哪些轮次的补时集中出现在下半场。这些结论都不是靠印象，而是靠每场都记录下来才能浮现的。
        </p>
        <p>
          专注一件事带来的好处很直接：您在任何时间点看到的补时数据，都来自同一套记录习惯，而不是不同赛季用不同方法拼出来的结果。
