一、④段整套同步（用户选候选 A）
- 新增 `references/stage-proto-doc/assets/产品文档模板.html`（16 KB／247 行，从备份拷、转 LF）。
- ④段 SKILL.md 换成备份 15:28 那版，并按模板口径改齐：
· 「产品文档框架」从「四块＋一附录」改成**六节** —— 页面结构／功能清单／使用场景／操作流程／
跨页与界面状态／待确认与偏离；与模板同构，⛔ 不从空白页重写结构。
· 编号从 R/S/F 改成 **P 页面／S 场景／F 功能／J 二级功能**，各自唯一、按展示顺序通排。
· 保留旧版有价值的要求：每项功能补齐 做什么／入口在哪／输入边界／异常与恢复；重点功能三处标红；
横向流程图每步写清页面／功能／操作／完成判据。
· 完成标准「七节」→「六节」，自查清单同步换掉「需求」那批条目，补模板与配图两条。
· 路径 `designs/<项目>/` → `docs/pm/<项目>/ui/`（2 处）。
· 补回本机那条「每份产出文档开头都要有一张图」的引用（指向主 skill，段内不复述）。
- 主 skill 同步：四段结构表④行、④段沿革、画图小节（④段画页面结构图 ＋ 用户路径）。
二、open-design 移到技能根（用户选候选 A）
- `git mv product-planning/references/stage-delivery/assets/open-design → open-design/`（4178 文件）。
- `.gitignore` 白名单加 `!/open-design/` —— 否则移出去就不再纳入版本控制。
- 引用改 11 处：路径形态 `assets/open-design/...` → `<技能根>/open-design/...`；
「随段携带的自带件」改称「同根技能」；「路径怎么找」那条改成自带件（段内相对路径）与
同根技能（`<技能根>/<技能名>/`）两类分开写。
- open-design 自己的 ATTRIBUTION.md 两处同步（它现在与 oil-ui-pro 同层）。
- 副作用（有益）：命名闸门读数由 2063 降到 225 —— 此前它把 open-design 里 919 个第三方 md
当成规则一起扫了；现在只扫本包 23 个 md。已确认④段的 H1 与 4a/4b/4c 子步仍在检查范围内。
三、验收
- check_naming.py --ws E:/ProgramData/AIProject/contentm_agent ＝ 通过 225 / 失败 0 / 提示 27。
- 活文件里 `assets/open-design` 残留 0；工作区 CRLF 文件 0。

Design System Inspired by Coinbase
Category: Fintech & Crypto Crypto exchange. Clean blue identity, trust-focused, institutional feel.
1. Visual Theme & Atmosphere
Coinbase's website is a clean, trustworthy crypto platform that communicates financial reliability through a blue-and-white binary palette. The design uses Coinbase Blue (#0052ff) — a deep, saturated blue — as the singular brand accent against white and near-black surfaces. The proprietary font family includes CoinbaseDisplay for hero headlines, CoinbaseSans for UI text, CoinbaseText for body reading, and CoinbaseIcons for iconography — a comprehensive four-font system.
The button system uses a distinctive 56px radius for pill-shaped CTAs with hover transitions to a lighter blue (#578bfa). The design alternates between white content sections and dark (#0a0b0d, #282b31) feature sections, creating a professional, financial-grade interface.
Key Characteristics:
- Coinbase Blue (
#0052ff) as singular brand accent - Four-font proprietary family: Display, Sans, Text, Icons
- 56px radius pill buttons with blue hover transition
- Near-black (
#0a0b0d) dark sections + white light sections - 1.00 line-height on display headings — ultra-tight
- Cool gray secondary surface (
#eef0f3) with blue tint text-transform: lowercaseon some button labels — unusual
