/* TapeRelay 前端的样式 —— 2026-10-25 前端改版（往银行一样的坚固感走：铺满页面、少框、大圆角、独特的字体、配色、图标、动效、点缀）。
   版面：左边一条通高的海军蓝「金库栏」（标志、名字、导航，底部一枚防伪纹样），右边一整张大圆角白纸放内容，不再一块块套卡片。
   字体：中文标题思源宋体、数字和英文 Barlow，都随前端一起发布（见下面的 @font-face）；正文用系统的苹方、微软雅黑。
   图标和保险箱标志是 views/icons.mjs 自己画的行内 SVG，拨盘刻度是纯 CSS，防伪纹样用 canvas 现画：打开页面只请求本站的文件（ui/test/test-browser.mjs 要求）。原有页面上的文字、按钮的字都不变（测试按字找按钮）；新加的字只在首页仪表盘和显示设置里。 */
/* 字体（2026-10-25 前端改版）：开源字体随前端一起发布（ui/app/fonts/，SIL Open Font License，许可文件在同一目录）。
   标题用思源宋体（Noto Serif SC，只留界面里用到的字，粗、特粗两档）；数字和英文用 Barlow（照 DIN 的感觉设计）。缺的字退到系统字体。 */
