④段整套同步（六节 ＋ P/S/F/J ＋ 模板）＋ open-design 移到技能根

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。

+# Warm Editorial
+
+> Category: Starter
+> A serif-led magazine aesthetic. Terracotta accent on warm off-white paper —
+> good for long-form, editorial, and brand-led marketing pages.
+
+## Visual Theme & Atmosphere
+Warm, unhurried, magazine-like. Think "a New Yorker interview column online." Generous whitespace, long-form readability, restrained chrome. Playful but never novelty.
+
+## Color Palette & Roles
+- **Background:** `#FAF7F2` (warm off-white paper)
+- **Foreground:** `#1C1A17` (near-black, slightly warm)
+- **Accent (primary):** `#C0512F` (terracotta) — used for links, primary CTAs, 1 hero element max per page
+- **Accent (secondary):** `#2F5B4F` (forest) — section dividers, tags
+- **Muted:** `#8A817A` (mid-warm-grey) — timestamps, metadata
+- **Surface:** `#FFFFFF` — elevated cards only
+Never use pure black or pure white anywhere user-facing.
+
+## Typography Rules
+- **Display / headings:** "GT Sectra" or fallback serif (`'GT Sectra', 'Times New Roman', serif`)
+- **Body:** "Söhne" or fallback sans (`'Söhne', -apple-system, system-ui, sans-serif`)
+- **Mono:** `'JetBrains Mono', ui-monospace, monospace` for code only
+- Scale (px): 12 · 14 · 16 · 20 · 28 · 40 · 56 · 80
+- Line-height: 1.6 for body, 1.2 for display
+- Letter-spacing: -0.02em for display sizes above 40px; default elsewhere
+
+## Component Stylings
+- **Buttons:** flat fill, 12px radius, 14px padding-block, 20px padding-inline. Primary = terracotta fill, off-white label. Secondary = outlined 1px foreground, transparent fill.
+- **Cards:** off-white background, 1px forest-at-8%-opacity border, 16px radius, 24–32px internal padding. No shadow except hover (y+2px, blur 16, foreground-at-6%).
+- **Inputs:** underline only (no box), 1px muted baseline, terracotta baseline on focus, 16px vertical padding.
+- **Links:** terracotta, 1px terracotta-at-40% underline, no underline on hover (swap for terracotta-at-8% background).
+
+## Layout Principles
+- 12-column grid, 1200px max-width, 24px gutters.
+- Hero sections: 72vh minimum, 120vh maximum. Content top-biased, never centered vertically.
+- Body sections: 80px top+bottom spacing at desktop; 48px at tablet; 32px at phone.
+- One accent color per screen. If a page has a terracotta hero, secondary CTAs are foreground-only, not forest.
+
+## Depth & Elevation
+Minimal. Only two elevation levels:
+- **Flat (0):** everything by default.
+- **Raised (1):** cards on hover, dropdown menus, floating CTAs. 2px y-offset, 16px blur, foreground at 6% opacity.
+No shadows on inputs. No shadows on the hero. No neumorphism, no glassmorphism.
+
+## Do's and Don'ts
+- ✅ Let whitespace breathe. A short headline on 50% of the viewport height is correct.
+- ✅ Use serif for numbers when they matter (pricing, stats).
+- ✅ Draw one accent element per page; the rest is foreground.
+- ❌ No gradients.
+- ❌ No emojis in product copy.
+- ❌ No sentence-case for headings — use title case for H1/H2, sentence case for H3 and below.
+- ❌ No border-radius above 24px; no border-radius below 8px.
+
+## Responsive Behavior
+- **Desktop ≥ 1024px:** 12-col grid, full hero heights, side-by-side columns.
+- **Tablet 640–1023px:** 8-col grid; hero drops to 60vh; columns stack at 3+.
+- **Phone < 640px:** 4-col grid; single-column layout; hero drops to 50vh; all padding -33%.
+
+## Agent Prompt Guide
+When generating artifacts against this design system:
+- Lead with typography and whitespace; chrome (borders, shadows) is subtractive.
+- If you need more than one accent element on a screen, you're doing too much — cut one.
+- When asked for "professional" or "serious," lean harder on serif + whitespace. When asked for "modern," this system isn't the right answer; pick a different DESIGN.md.
+- Color tokens are non-negotiable. Do not invent new hex values. If the request needs a color outside this palette, produce a warning comment in the artifact and use the closest existing token.
+- Prefer 1 hero + 3–5 body sections over 1 hero + 8+ sections. Editorial means restraint.
