   不器·此物 · 老钱视觉体系（v5 · 2026-09-11）
   对标 Hermès / Bottega Veneta：摄影称王、UI 隐形。
   纯 HTML + CSS，零脚本。交互仅 :hover / :focus-within /
   checkbox 状态与 <details>。
   字体：Noto Serif SC（中文宋体，细字重）+ Cormorant Garamond（拉丁，300），本地自托管。
   视觉：暖纸白近中性底 + 全出血暗调电影摄影 + 极细中性线 + 超大留白；
         无装饰花纹、无实心彩色按钮——CTA 全为下划线文字链接；颜色只在照片里。
