Horldsence fd71b83e3a reference: 早先那版 C 写的装甲板固件(ESP-IDF 工程)
`armor/` 是它的 Rust 改写版,这一份留着当参考:ADC 阈值的 2000 就是从它标定出来的
(`.env.example` 里那句 "same as the reference firmware" 指的就是它),而且它的 README
记着实测设备与 MAC,换硬件时是有用的现场记录。

只收了 20 个源文件。它自带的 `.gitignore` 已经排掉 `build/`(211 MB 的 ESP-IDF 构建产物)
与生成的 `sdkconfig`,所以仓库里不会多出这些东西。

两处顺带处理:
- `reference/armor/.git` 是一个**空的**仓库壳(`git init` 过,零提交、零 remote、零 ref),
  而外层 git 正因为它的存在而拒绝索引 `reference/` 下的任何文件
  (`error: 'reference/armor/' does not have a commit checked out`)。它被挪到
  `desktop/.dev/backup/reference-armor-git`(可逆,且该目录已被忽略),不是删除。
- 它的 README 指着 `../armor-platformio-backup/`,那份备份并不存在。改成明说"没有进仓库",
  免得以后有人照着找一个不存在的目录。

另外把 `/docs/` 加进 .gitignore:那是工作区里另起的一个 Astro 文档站,与本仓库无关。
