新闻资讯板块 · 改造预览

保留 h3 大标题 + .tips 副标题的位置与样式不变（padding-top:70px、h3 40px/800、tips 18px #5e6470），只改主体 .messageCont 部分。

改造方向：左列加装饰序号 + 右列精选图上叠加信息，整体从「公司简介感」变成「杂志专题感」。配色沿用站内三色体系（品牌橙 #ff6726 / 近黑 #1f2329 / 次要灰 #6b7280），不引入新色。

改造点对照

三个必须注意的硬约束（来自你的清单）

1. .newItem 必须保留 min-width: 0——虽然这次没用 white-space:nowrap 的 .lineText，但 .title 用 -webkit-line-clamp:2 也有同样的撑宽风险。grid 布局里 minmax(0, 1fr) 已经兜住左列，右列显式定宽不参与撑开。
2. AboutNewsFooter 里还有 #about——只改 .messageBox 相关规则，别碰 .aboutBox；新增的选择器都以 .messageBox . 或 .newItem / .item 开头，不会误伤。
3. pageTitle 是共用组件——本次只用了 .messageBox .pageTitle { padding-top: 70px } 已有覆写，没有新增对 h3 / .tips 的规则，PageTitle 入场动画不受影响。

建议顺手修的两件事

• 精选位不该锁死「第 3 条」：把 const feature = currentNews[2] 改成 currentNews.find(i => i.coverMedia) ?? currentNews[2]——保证精选位永远有图，避免长标题 + 无封面随机炸版式。
• 默认图接上后台：/media/news-placeholder.svg → themeText(settings, 'theme.news_default_image', '/media/news-banner.png')，这样后台改默认图首页跟着变。

如果需要，我可以再给一个「1 大 + 3 小」的更激进版（左列 3 条纯文字、右列精选图更大、甚至加一个分类色标签栏），但那个要重做断点表。目前这版是在现有 flex/grid 结构上做视觉升级，改动量最小、回归风险最低。
