/* templateicl1 / D 杂志分区式 / build 2026-09-09 cl1-v4
 * 参考站：cricfytvap.net | 原创 cl1- 前缀 + 原创色值
 * 主色 #e06818（暖琥珀橙，异于参考 #ef6b06 / templatein22 #e67012）
 * v2：增补正文自带 details/summary（AI 内容原生 FAQ）样式，对齐 Kadence accordion 视觉基因
 * v3：修复按钮/nav 链接色被 `.cl1-body a`（特异性 0-1-1）覆盖成橙底橙字；首页 h2 负上边距贴 zone 顶成分区头带（消除与正文分离感，odd zone 换差异色增强分区边界）；手机端 zone 左右内边距 16→20px
 * v4：手机端 zone 左右内边距 20→24px（v3 变化小无感知）、header 左右同步 16→20px；h2 负边距同步 -24px（JS initZones 重写见 main.js v4）
