需求：Mac 端 installer 體驗類比 Windows .exe — 進 DMG 就看到漂亮的視窗
背景 + 拖到 Applications 的視覺引導。
實作：
- installer/macos/ 新資料夾
- make-dmg-background.py：動態生成 640×400 深色背景，配色對齊 Wails
控制台 splash（#111827→#0B0F19 漸層 + #38BDF8 accent）
- background.png + background@2x.png（1x + 2x Retina）
- Makefile dmg 拆三 target：
- dmg：auto-detect，有 create-dmg 走 fancy，沒有 fallback plain（CI 無痛）
- dmg-fancy：強制美化版（需 `brew install create-dmg`）
- dmg-plain：原 hdiutil UDZO（保留為 fallback）
- Windows / Linux 流程零改動
驗證：
- `make dmg-fancy` 產出 157MB DMG，mount 後內容：app + Applications 捷徑
+ .background/background.png + .DS_Store（視窗樣式）
- `hdiutil verify` 通過

生成 DMG 美化背景圖（640×400），對齊 Wails 控制台深色 splash 風格。

用法：
|

python3 installer/macos/make-dmg-background.py
|
||
|

輸出：
|

installer/macos/background.png (1x, 640×400)
|

installer/macos/background@2x.png (2x, 1280×800 Retina)
|

create-dmg 會自動挑 @2x 版本用於 Retina 螢幕。
