/* ============================================================
 * editorial.css — 首页编辑排版皮肤 v2（S2 oiloil 风格改造）
 * 设计语言（对齐 oiloil.org 实测）：
 * - 奶油纸底 + 淡格纹 + 左上暖黄光晕
 * - 白色大圆角浮卡、极淡阴影，无硬边无黑块
 * - 分区头 =「—— 中文 / MONO-EN」+ 巨型描边幽灵数字
 * - 文章 = 行式列表（编号 + 标题 + 日期 + 箭头），可无限扩展
 * - 等宽字体注记、单一暖色强调、大量留白
 * 结构与类名与 e2e 契约一致，只换视觉语言。
