   Scent & State — 设计系统
   ══════════════════════════════════════════════════════════════════
   取向：**编辑型科学刊**。枢纽站是知识站，视觉上要「可信、克制、有辨识度」，
   不要促销感。所以：
     · 暖白纸底 + 铜色强调 + 深墨字，不用高饱和品牌色
     · 标题用衬线（编辑可信度），正文用系统无衬线（可读性）
     · 每个词群一个色相（--h），从磁贴、卡片、文章主视觉一路贯穿
     · 主视觉全部是内联几何 SVG，零外部请求（不依赖图床 / 不引 web font）
