/* ==========================================================================
 * 商标注册费用计算器 /tool/trademark-fee-calc
 * 视觉主题：商标局打样台 · 油墨青 + 专色橙红
 *
 * 设计隐喻：商标的本质是「图样 + 颜色 + 类别」，所以整页按「印刷打样 / 色卡」
 * 来造：尼斯 45 类 = 45 个色卡卡位，规费明细 = 打样单，生命周期 = 印刷工单刻度，
 * 三种申请方式 = 三张并排小样，批量对比 = 拼版表。
 *
 * 色系与站内其它工具全部错开：不用朱砂红、不用黛青墨绿、不用翡翠金、不用靛紫。
 * 作用域限定在 .tf-page，变量前缀 --tfc-，不会污染其它页面。
 * 深浅双主题：浅色写在 .tf-page 上，深色覆盖用 :root[data-theme="dark"] .tf-page。
 * （站内主题按钮 light 时会移除 data-theme 属性，所以浅色=无属性是唯一基线）
