/* ====================================================================
   刷机教程统一版式（Help1 ~ Help5）
   --------------------------------------------------------------------
   改版目标只有一个：让教程「好读」。
     * 每页开头一句话说清「这篇解决什么问题」；
     * 步骤不再是挤在一起的大段文字，而是一步一张卡片（左边圆号）；
     * 重要提醒用四种颜色的提示块区分「注意 / 警告 / 危险 / 成功」；
     * 左侧常驻教程目录，随时能在 5 篇之间跳，底部有上一篇 / 下一篇。
   设计上沿用站内的浅蓝 + 浅紫配色，不引入新的视觉语言；
   类名统一 help- 前缀，避免与 main.css / rom.css 的既有类名冲突。
