/*
 * css/app.css — 全站样式（和纸 / 墨 / 朱印）
 *
 * 核心逻辑：底色是纸，字是墨，唯一的高饱和色是朱。势力颜色由数据带过来（内联 style），
 *           这里只定义纸面、字阶、发丝线与留白。
 * 关键决策：
 *   1. 分区靠留白和 1px 发丝线，不靠深色方块堆叠 —— 深色面板是「后台管理系统」的
 *      观感，这个项目要的是「一册正在被写的编年史」。
 *   2. 明朝体（Noto Serif SC）承担标题与叙事，黑体（Noto Sans SC）只放数字和小标签。
 *      小标签一律宽字距，西文小写转大写，这是整套版式的呼吸感来源。
 *   3. 纹理、印章、刻度全部是 CSS 渐变与边框画的。真正的图片素材（纹章、君主像、
 *      城池远景）走 /img/ 渐进补齐，没到位时一律有排版兜底 —— 缺图要看起来是有意的。
 *   4. 改这个文件后必须 bump inc/header.php 里的 ASSET_VER。
 * 依赖：无。
 *   5. S2 起页面上有了第一个按钮（派出车队）。按钮也不许破坏纸面：不是实心方块，
 *      是一枚朱色边框的小印，按下去才填实。整站唯一的高饱和色仍然只有朱。
 * 本次改动：S2 加「补给线」一节的样式。
