高效适配多屏幕的横向时间线实现方案

问题痛点

当前基于3800px宽屏实现的时间线，用Grid/Flex搭建外观、伪元素生成垂直线条，但文本框依赖手动position定位，屏幕尺寸变化时需反复调整，维护成本极高，急需适配性更强的实现方式。

优化思路

语义化重构HTML：将每个时间节点的图标、日期、内容封装为独立单元，结构更清晰，便于样式关联。
Grid自动对齐布局：利用Grid的列对齐特性，让内容框自动依附对应日期节点，彻底告别手动定位。
响应式自适应：通过媒体查询调整Grid列数、内容宽度，实现不同屏幕下的无缝适配。

优化点说明

语义化结构：每个时间节点封装为<article>，结构清晰，便于后续维护和扩展。
自动布局：通过repeat(auto-fit, minmax(200px, 1fr))实现列数自动适配，内容框用nth-child实现交错排列，无需手动定位。
响应式字体：用clamp()函数实现字体大小随屏幕自动缩放，避免固定尺寸导致的溢出或显示过小问题。
统一样式管理：颜色提取为独立类名，避免重复代码，修改颜色只需调整类样式。
简化线条实现：垂直线条高度统一设置，通过内容框的margin-top控制间距，无需手动计算百分比高度。
