/* 传家 Heirloom Stories · 官网第三版共用样式(2026-10-06,staging,未发布)
   版式:照苹果中文官网 AirPods 页的节奏与字号层级(首页风格G「丁二」定稿)。
   字体排版:全部照 apple.com.cn 实测值(字号/行高/字重/字距,大中小三档断点 1068 / 734),2026-10-07 Max 定;
   不为长辈放大字号(买书的人是 30 到 40 岁)。字重只用 400 和 600。
   颜色:整页固定白底,不随手机深色模式变黑;黑白灰为主。
   全页只有一种颜色「回忆色」焦糖 #a0602a:只给「当下的动作」——
   电脑鼠标移上去、手机手指按下、键盘选中、正在播放/正在录音,以及播放时老照片回到彩色。
   「回忆是黑白的,当下是彩色的。」别处一律不用颜色。
   英文版以后加:字体栈已含西文字体,文字不写死在样式里。 */
