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。

+# Checklist — Waitlist Page
+
+## P0 — Must pass before emitting `<artifact>`
+
+- [ ] Page has exactly one primary CTA (the email field + submit button)
+- [ ] No hero gradient that spans more than 20% of the viewport height
+- [ ] Email input has a visible label or meaningful placeholder — not just "Email"
+- [ ] No invented social proof numbers (e.g., "10,000 people waiting")
+- [ ] **No countdown timer present** — countdown timers are an explicit anti-pattern for this skill (see SKILL.md §Quality gates)
+- [ ] No horizontal scroll at 375px viewport
+- [ ] No generic emoji icons used as decorative elements
+- [ ] Typography uses at most two font families (display + body)
+- [ ] First name field has no `required` attribute
+- [ ] Work email field has `type="email"` and `required`
+- [ ] Form does **not** use `novalidate`; JS guard calls `checkValidity()` before showing success state
+- [ ] Success message uses `role="status"` or `aria-live="polite"` so screen readers announce it
+- [ ] All color values derived from DESIGN.md; only allowed hardcoded exception is `#2D6A4F` for `--success`
+- [ ] All user-supplied text tokens are HTML-escaped; color tokens adhere to strict grammar (`#hex`, `rgb/hsl/oklch`, `color-mix()`) and contain no unsafe characters (`;`, `{}`, `<`, `>`, `/*`, `@`, `url(`); font name tokens are URL-encoded in the Google Fonts URL; `{{LOGO_MARK}}` is escaped text initials or strictly sanitized inline SVG (no scripts/events)
+
+## P1 — Should pass for quality submission
+
+- [ ] Hero section is visually distinct and above-the-fold
+- [ ] Email submit button has hover and active states
+- [ ] Form validation provides clear inline feedback on error (native `reportValidity()` is acceptable)
+- [ ] Page is scrollable (not clipped) at 375×667 and 390×844; CTA visible without scroll at those sizes
+- [ ] Ticker animation is paused or removed under `prefers-reduced-motion: reduce`
+- [ ] All interactive elements have visible focus styles (not just `outline: none`)
+- [ ] Keyboard: Tab reaches each form field and the submit button; Enter submits the form
+- [ ] Color contrast of body text on background meets WCAG AA (≥ 4.5:1)
+- [ ] Color contrast of button label on button background meets WCAG AA (≥ 4.5:1)
+- [ ] Color contrast of logo text/initials on logo container background meets WCAG AA (≥ 4.5:1)
+- [ ] Logo alt text or `aria-label` present if logo is an `<img>` or meaningful SVG
+- [ ] Ticker ribbon has `aria-hidden="true"` (decorative, not meaningful content)
+- [ ] `<html lang="">` attribute is set to the correct language code
+
+## P2 — Nice-to-have polish
+
+- [ ] Google Fonts loaded with `display=swap` to avoid FOIT
+- [ ] Form inputs have matching `autocomplete` attributes (`given-name`, `email`)
+- [ ] Subtle micro-animation on button hover (scale or opacity only — no layout shift)
+- [ ] Decoration zone does not cover or overlap the form at any viewport width
+- [ ] Page title is `{{PRODUCT_NAME}} — Coming Soon`, not a generic placeholder
