/* ============================================================================
   Taoify Theme Kit —— 模板库共用组件层
   ----------------------------------------------------------------------------
   一套模板一个 <style>（只管自己的配色和版式），其余全部来自这里。
   这样 117 个模板不必各写一遍页头、页脚、底部导航、商品卡，改一处全站生效。

   用法（模板页里）：
     <link rel="stylesheet" href="/Asset/theme-kit/kit.css">
     <style>body{--tk-accent:#B4633F; ...}</style>
     ... {{>kit_header}} ... {{>kit_footer}} {{>kit_tabbar}} {{>kit_js}}

   约定：
   - 变量全部带兜底值，模板只覆盖想改的那几个；
   - 唯一断点 992px，再往下一档 600px；不做 768 这类中间档，避免三套主题各写各的；
   - 可点区域统一 44px（--tk-tap），价格用等宽数字，focus 有可见描边；
   - 媒体查询一律写在文件末尾，避免同权重被后面的基础规则盖掉（踩过）。
