r"""交付文档图表构建器（需求分析 / 系统设计说明 / 数据要求说明 三份 docx 的插图）。

## 为什么单开一个器
三份交付文档要求"文表图并茂"。图里出现的每个数字都必须能追到仓库里的真件，所以图**不手画**：
本器从 `src/version.py` 的 HISTORY、`configs/portal_pages.yaml`、`configs/serve.json`、
`data/raw/<场>/**`、`outputs/<场>/**` 与 `guanlan.py check` / `rebuild_all.py --dry-run` 的**实跑输出**
里取数，落到 `docs/figures/*.png`。纯示意图（架构/链路/时序）也在图注里写明"依据"。

## 落点与口径
    docs/figures/fig-req-01..04 / fig-des-01..06 / fig-dat-01..04 .png
    docs/src/_guanlan_check.txt        （验收门实跑原文，图的取证底稿）
    docs/src/_rebuild_plan.txt         （重算链 dry-run 原文，图的取证底稿）

## 用法
    python scripts/delivery_docs_figures.py            # 全画
    python scripts/delivery_docs_figures.py --only req # 只画某一组 (req/des/dat)
    python scripts/delivery_docs_figures.py --check    # 只报缺哪些图

退出码: 0 全部生成 · 5 有图没生成（源件缺或绘图失败，逐条打印原因）
