OS4 Icons —— S5 图标包 -> S4 eSIM
界面按 CSS 设计稿 1:1 落地（本机用真 MiSans 字体渲染预览验证过）:
* 页面底色纯黑（取自封面图四角）
* rgba(255,255,255,0.6) -> #999999（白 60% 叠黑）
* font-weight 600 -> MiSans-Semibold ; 500 -> MiSans-Medium
* vertical-align:middle -> 手工算 y（LVGL 标签没有垂直居中样式）
* 多色文本用 LVGL recolor："灰#ffffff 白#灰"
* 圆屏安全区：实测所有页面 0 像素越界（大按钮全靠 40px 圆角收进圆内）
真机已验证的底层能力:
* 宿主不调用 ui.init -> 加载期建界面
* SCRIPT_PATH 为空 -> 用 debug.getinfo 反推目录
* .face 不解包，资源仍在 resource.bin 里 -> 按偏移读出来用
* /dev/app 可写，dd 读写校验通过
* 没有 utf8 标准库 -> 自带按位 UTF-8 解码（本文件未用到，留作提醒）
