/**
 * 新闻正文内容样式
 * ================
 *
 * 为什么需要这个独立文件
 * ----------------------
 * news-detail.html 原本把正文样式写在 <style type="text/tailwindcss"> 里，
 * 但该页面加载的是「预编译」的 tailwind-index.css，并未引入
 * cdn.tailwindcss.com（Tailwind Play CDN）。浏览器无法识别该 type，
 * 会整块忽略这段样式，导致正文里的表格、图片、标题完全没有样式。
 *
 * 本文件是普通的 <link> 样式表，浏览器必定生效。
 *
 * 统一用 #news-content 限定作用域：ID 选择器特异性高于 Tailwind preflight
 * 的元素选择器，可稳定覆盖 preflight 对标题 / 列表 / 引用的重置。
 */

/* ========== 页面装饰类（原 type="text/tailwindcss" 死代码块迁出） ==========
 * 这些类原本写在 news-detail.html / news.html 的 <style type="text/tailwindcss">
 * 里，因缺少 Play CDN 而全部失效。现统一沉淀到普通样式表，
 * 两个新闻页共用，保证观感一致。
