/*
 * PM98 修复：从 base.html 抽离的站点主题样式
 *
 * 说明：
 * - 本文件从 base.html 内联 <style> 中抽离（原第 103-924 行），约 820 行纯静态 CSS。
 * - 所有 var(--xxx) 变量在 base.html 内联的 :root 块中定义（依赖 settings 表动态注入），
 *   因此必须确保 base.html 在引用本文件之前已加载 :root 变量定义。
 * - 加载顺序：style.css（基础） → :root 变量（内联，含 Jinja） → theme.css（本文件） → extra_css（子模板扩展）
