/* ==========================================================================
 * 遗嘱订立与见证公证费用计算器 /tool/will-draft-cost-calc
 * 视觉主题：信笺手书 · 钢笔蓝 + 火漆
 *
 * 设计隐喻：遗嘱是「写给最后的人的信」，公证是「火漆封缄」。
 * 因此整页按手写信笺来造：费用印鉴做成圆形火漆印章，卷宗目录做成手写折页标签，
 * 家谱用钢笔线条绘制，卷宗内页带淡蓝横线与左侧装订红线。
 *
 * 色系与站内其它工具全部错开：不用朱砂红、不用油墨青、不用翡翠金、不用靛紫。
 * 作用域限定在 .wd-page，变量前缀 --wd-；深色覆盖用 :root[data-theme="dark"] .wd-page。
 * （站内主题按钮 light 时会移除 data-theme 属性，故浅色=无属性是唯一基线）
