/* =========================================================
   theme-senior.css — 适老可读优先 覆盖层
   ---------------------------------------------------------
   在主色板基础上做三件事：
     1) 提高对比度（正文更深、次要文字不用浅灰）
     2) 放大字号与行高（基准 17px → 18.5px）
     3) 放大点击热区（按钮/选项/输入不低于 48px）
   办法：重声明同名 CSS 变量 + 用同选择器覆盖，不用 !important。
