   前缀刻意不叫 gb- —— 那会让「触摸屏页面上出现 gb-hero」变成下一个误读源。

   Hallmark · genre: modern-minimal · macrostructure: Split Studio
   theme: 站点既有色板(hex,紫) · enrichment: 客户实拍图
   nav/footer: 站点既有(阶段二重构后的贴右报头 + 陈述/著录页脚)
   说明:字体对(Archivo + Inter)与 hex 色板沿用仓库现状,不引 OKLCH、不换字体;
        配色只用实色与同色相 —— 站点是紫+青,而紫→青渐变是被明令禁止的组合。
   间距:本页首次引入刻度(全站其余仍是散落 px,迁移另议)。
