@ -421,163 +421,3 @@ Send Engine 最終態（terminal）：
 建議：
 - 做「最終寄出 HTML 預覽」功能，預覽管線與正式發送使用同一套 renderer。
 - 後續可加多裝置寬度與常見 email client 快速檢視模式（若使用者回饋有需要）。
-
-## 10. 電子報「類型化編輯」設計分析與實作計劃（2026-05-13）
-
-需求摘要（已確認）：
- 建立電子報時，先選「電子報類型」再進入編輯。
- 每種電子報類型有預設 template，但允許使用者改模板。
- 既有類型：`通用電子報`（自由編輯內容）。
- 新增類型：`每週新聞電子報`（選文章組版）。
- `每週新聞`除模板與文章選擇外，還要有「單則新聞 HTML 樣式」：
-  - 系統提供預設值。
-  - 每封電子報可覆寫（通常不改，必要時可改）。
- 預覽功能必須保留，且要反映「套模板後最終結果」。
- 後續新增定型電子報，接受「需要改程式」。
-
-### 10.1 可行性結論
-
-可行，且建議採「類型策略（type strategy）」實作：
- 資料層只新增最少欄位承載「類型 + 類型專屬設定」。
- 組版/預覽/發送統一走同一組 renderer 介面，依類型分派。
- 後續加新類型時，不改既有類型流程，僅新增一個 renderer + 後台欄位配置。
-
-### 10.2 目標操作流程（UX）
-
-1. 使用者在 Snippet 列表按「新增電子報」。
-2. 第一步顯示「選擇電子報類型」頁：
-   - `general` 通用電子報
-   - `weekly_news` 每週新聞電子報
-3. 選類型後進入對應編輯畫面（或同畫面動態顯示對應欄位）。
-4. 系統帶入該類型預設 template（可改）。
-5. `weekly_news` 類型需額外完成：
-   - 選文章（可多選、可排序）
-   - 單則新聞樣式（預設值 + 可覆寫）
-6. 預覽按鈕顯示最終結果（文章內容 + 單則樣式 + 外層模板）。
-7. 發送時使用相同 renderer，避免預覽與實際寄送不一致。
-
-### 10.3 資料模型規劃（最小變更）
-
-建議在 `NewsletterCampaign` 新增：
- `campaign_type`（CharField）
-  - choices: `general`, `weekly_news`
-  - default: `general`
- `item_template_html`（TextField, blank=True）
-  - 用於 `weekly_news` 單則新聞樣式覆寫
- `content_config`（JSONField, default=dict, blank=True）
-  - 先用於存 `weekly_news` 文章清單與排序資訊
-  - 範例：
-    - `{"article_page_ids":[123,456,789]}`
-
-建議在 `NewsletterTemplate` 新增（可選，但推薦）：
- `template_type`（CharField）
-  - 用於限制模板類型對應（避免 weekly 套到不相容模板）
-  - 若先求快可不加，先用通用模板 + placeholder 規範。
-
-建議新增「類型預設設定」來源（二選一）：
-1. 快速版：在程式常數定義每種類型預設值（包括預設 item template）。
-2. 長期版：加 `NewsletterTypeSettings`（Wagtail setting/snippet）供後台改預設值。
-
-### 10.4 渲染與發送策略（核心）
-
-新增 renderer 介面（概念）：
- `build_campaign_body_html(campaign) -> str`
- `build_campaign_body_text(campaign) -> str`
- `build_preview_html(campaign_or_payload) -> str`
-
-類型分派：
- `general`：
-  - 直接沿用既有 `html_template` / `text_template` 流程。
- `weekly_news`：
-  - 讀 `content_config.article_page_ids`
-  - 載入文章（標題、連結、摘要、封面等）
-  - 以 `item_template_html` 逐筆渲染並串接成 `email_body`
-  - 再套外層 `newsletter_template.template_html`
-
-注意：
- 預覽 API 與發送 job 必須共用同一 renderer。
- 不把套完外層模板的結果存回 DB（維持既有原則：預覽/發送當下組裝）。
-
-### 10.5 後台表單與互動規劃
-
-#### A. 建立流程（先選類型）
- 做法 1（推薦）：客製 `CreateView`，先顯示 `campaign_type`，提交後導到 edit。
- 做法 2：進 create 頁先顯示全欄位，但用 JS 依 `campaign_type` 切換可見區塊。
-
-#### B. `general` 欄位
- 顯示：`subject_template`, `html_template`, `text_template`, `newsletter_template`
- 隱藏：`weekly_news` 文章選擇區與 item template（或只讀）
-
-#### C. `weekly_news` 欄位
- 顯示：
-  - `newsletter_template`
-  - 文章選擇器（多選 + 排序）
-  - `item_template_html`（有預設值，可覆寫）
-  - （可選）`subject_template`（若空可由 template 預設 subject 帶入）
- 隱藏：
-  - 自由編輯 `html_template`（或改成唯讀顯示最終組版來源）
-
-### 10.6 預覽功能規劃
-
-新增/調整 preview endpoint：
- 接收 `campaign_type` 與對應 payload。
- `weekly_news` 預覽時直接用目前畫面文章清單 + item template 組版，不必先存檔。
- 回傳最終 HTML（已套外層模板、已替換示例變數）。
-
-### 10.7 每週新聞（Weekly）預設單則樣式建議
-
-預設 `item_template_html` 建議包含：
- `{{article_title}}`
- `{{article_url}}`
- `{{article_cover_url}}`
- `{{article_intro}}`
- `{{article_date}}`
-
-建議 fallback 規則：
- 無封面圖：隱藏 `<img>` 區塊或改用預設圖。
- 無摘要：顯示標題 + 連結即可。
-
-### 10.8 實作步驟（建議）
-
-1. Model + migration
- `NewsletterCampaign` 新增 `campaign_type`, `item_template_html`, `content_config`。
-
-2. Admin form / panels
- 先選類型流程（create view）+ 欄位顯示切換。
- `weekly_news` 文章選擇與排序 UI（第一版可先用簡單多選）。
-
-3. Renderer
- 抽出 `general` / `weekly_news` 共用入口。
- 串入 preview API 與 send scheduler。
-
-4. Preview
- 擴充現有 preview compose 邏輯，使其依 `campaign_type` 分派。
-
-5. Send
- `_build_send_job_payload` 改為依 renderer 組 body，再送 Send Engine。
-
-6. 測試
- `general` 回歸測試（不可壞）。
- `weekly_news` 組版、預覽、發送一致性測試。
-
-### 10.9 風險與控管
-
-風險：
- 類型欄位加入後，既有 campaign 資料相容性。
- preview 與 send 使用不同邏輯導致內容不一致。
- 文章多選排序 UI 複雜度偏高。
-
-控管：
- 既有資料 migration 一律補 `campaign_type='general'`。
- renderer 單一路徑，preview/send 共用。
- `weekly_news` 第一版先做可用，再迭代進階排序體驗。
-
-### 10.10 後續新增定型電子報的擴充規範
-
-每新增一種類型至少變更：
-1. `campaign_type` choices
-2. 該類型後台欄位配置
-3. 該類型 renderer
-4. 該類型 preview payload 驗證
-
-此規範符合「新增定型電子報需要改程式」的產品決策，且可保持改動局部化。
