MeowOS for HiBy R3 Pro II — 公共发布版本（历史已重置）
• 全新单提交：清除含敏感信息的旧历史（sudo 口令、内网 IP、SSH 密钥路径、热点 SSID、设备 MAC） • 本地开发文档/测试记录/构建脚本全部移入 gitignored 的 devdocs/ 与 scripts/build/（不入库） • 保留：MeowOS 源码（launcher/watchdog/bootmenu/meow_svcd/SDK）、项目规范文档、mips-repo 增补组件：SDK 统一日志+通知 API、meow_svcd 服务管理器、mips-repo 软件仓库

# gen_ui_font.py — 预渲染 MeowOS UI 位图字库（替代 freetype，零依赖）
|
||||
#
|
||||
# 输入默认字体（本脚本用设备自带 default.otf，因为 ~/Fonts 属主为 10195 不可读；
|
||||
# 如需切换思源黑体/MiSans，改 SRC 路径并把字体拷到可读处，或经 meow.conf font_file= 指定）。
|
||||
# 输出 ui_font.dat：自定义二进制位图字库（8-bit alpha 灰度，白字用 alpha，blit 时着色）。
|
||||
# 布局（小端）:
|
||||
# +0 uint32 magic "UIF1"
|
||||
# +4 uint16 px (设计字号，用于行距/参考)
|
||||
# +6 uint16 flags (0 = 8-bit alpha 灰度)
|
||||
# +8 uint32 n (glyph 数)
|
||||
# +12 uint16 atlas_w (位图集宽)
|
||||
# +14 uint16 atlas_h
|
||||
# +16 16*n entry: uint32 cp; uint16 x,y,w,h,adv
|
||||
# +16+16*n bitmap: atlas_w*atlas_h 字节（8-bit alpha）
|
||||
#
|
||||
# 字符集：ASCII 0x20-0x7E + GB2312 一级汉字(0xB0-0xD7) + 常用 CJK 标点 + UI 显式字符串。
