/* ==========================================================================
   南京国际旅行社 · 官网主样式
   --------------------------------------------------------------------------
   设计方法：反「AI 套版」的编辑式设计
     · 不居中一切 —— 标题、段落一律左对齐
     · 衬线大字标题 + 戏剧性字号对比
     · 打破均匀网格（首卡通栏的杂志式布局）
     · 暖纸底 / 深墨字，不用纯白
     · 信号色极度克制：赭金只做编号、下划线、小方块记号；朱红只做价格与极小徽记
     · 直角或极小圆角、1px 细线、无阴影
     · 动效做减法：无滚动渐入、无悬浮位移、无卡片上移阴影
     · CSS 计数器自动编号（01 / 02 / 03）作章节记号
   配色依据：《南京市城市色彩控制导则》「梧桐素彩，锦绣妆花」
     暖灰纸底（梧桐素彩）/ 朝天宫朱红 / 云锦明黄 / 中山陵靛蓝 / 明城墙青灰
