/* ============================================================
   实验追踪 — 沿用 booking 的 "Soft Lab" 语汇（圆角、柔和面板、深色侧栏），
   主色换成石墨梅子色，一眼区别于预约系统的蓝绿 / 陶土 / 靛紫。
   不加载任何外部字体 / CSS / JS（用户在国内，外链失败会拖慢首屏）。
   对比度（WCAG，文字压在其底色上）：
     白字 / --primary        7.72   白字 / --primary-deep  12.14
     --ink-faint / --bg       5.05   --ink-soft / surface   6.95
     风险 #A0241C / #FBE4E1   6.25   关注 #7A4D00 / #FCEFC9 6.34
     正常 #1D6638 / #DEF1E4   5.92   超期 #9A3412 / #FDEBDD 6.3
   色条 / 形状（非文本，3:1）：红 4.88、黄 3.63、绿 3.58（对白底）。
   健康度永远是 形状 + 文字 + 颜色 三重编码，不靠颜色单独传达。
