/**
 * fsmag 头版 v9 版式层（2026-10-14）
 *
 * 站长：「第一街全站的版式设计再用点心，以前做的有点粗糙」。本层只管版式，不改内容与数据：
 *   1. 纸面统一：各版块一律白底，不再白／米白交替铺色带；版块之间只靠题头双线规分隔。
 *      副刊刊架是另一份刊物，保留一块浅灰底以示区隔。
 *   2. 栅格统一：版心 1200，12 栏思路（7+5 / 5+7 / 4×3），栏距 3rem；纵向节奏 3.25rem / 3.5rem。
 *   3. 字阶五级：头条 → 版块主推 → 次条 → 目录 → 元信息（日期一律等宽、栏目标签刊色衬线）。
 *   4. 图位：直角、无投影、无圆角；图在上时与文字左缘对齐；无封面不留空图位。
 *   5. 每个版块一种句式：精选＝大图主推＋三条次条；国际／社会＝图文主推（社会镜像）＋两栏目录；
 *      经济＝主推＋日期目录＋合作来源带；历史＝四栏图文横排。
 * 专用类 f9- 前缀；本文件在 HomeShell 中最后加载。
