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: lowercase` on some button labels — unusual
|
||
|
||
## 2. Color Palette & Roles
|
||
|
||
### Primary
|
||
- **Coinbase Blue** (`#0052ff`): Primary brand, links, CTA borders

|
||
|

## 5. Layout Principles
|
||
|
||
### Spacing System
|
||
- Base: 8px
|
||
- Scale: 1px, 3px, 4px, 5px, 6px, 8px, 10px, 12px, 15px, 16px, 20px, 24px, 25px, 32px, 48px

|
||
- Full (100000px): Maximum pill
|
||
|
||
## 6. Depth & Elevation
|
||
|
||
Minimal shadow system — depth from color contrast between dark/light sections.
|
||
|
||
## 7. Do's and Don'ts
|
||
|
||
### Do
|
||
- Use Coinbase Blue (#0052ff) for primary interactive elements
|
||
- Apply 56px radius for all CTA buttons
|
||
- Use CoinbaseDisplay for hero headings only
|
||
- Alternate dark (#0a0b0d) and white sections
|
||
|
||
### Don't
|
||
- Don't use the blue decoratively — it's functional only
|
||
- Don't use sharp corners on CTAs — 56px minimum
|
||
|
||
## 8. Responsive Behavior
|
||
|
||
Breakpoints: 400px, 576px, 640px, 768px, 896px, 1280px, 1440px, 1600px
|
||
|
||
