   Deficit Tracker（减脂日志）· 样式
   路径：tools/deficit-tracker/deficit-tracker.css
   ------------------------------------------------------------
   设计口径
     · 暗色为默认（和饮录 / 影阅一致），但**所有颜色都走 CSS 变量**，
       切到 .theme-light 时整页跟着变，不在规则里写死颜色；
     · 强调色用「赤字红」（--dt-accent），达成用绿（--dt-ok），
       放纵用琥珀（--dt-cheat），三色贯穿统计卡 / 进度条 / 状态点；
     · 打印与窄屏都要能用：@media (max-width: 860px) 把横向卡片
       压成竖排，@media print 去掉模态与阴影。
