# UbisamBase 셸 UI 개편 지시서

이 문서 전체를 Claude Code에 붙여넣고 "이 지시서대로 적용해줘"라고 요청하세요.

---

당신은 `UbisamBase` WPF 솔루션(.NET Framework 4.8, MVVM + CommunityToolkit.Mvvm)에서 작업합니다.
플랫폼 셸의 화면 디자인을 아래대로 교체하세요. **아래 §2의 파일 내용은 전문이 주어져 있으니 그대로 덮어쓰거나 새로 만드세요** — 임의로 재해석하거나 값을 바꾸지 마세요.

## 1. 무엇을 바꾸는가

- **좌상단**: 회사 로고(accent 사각형) + 회사명 `Brand` + 세로 구분선 + 장비명 `Title`(= `IAppSetup.GetAppName()`)
- **우상단**: 작은 날짜 + 큰 시계(25px). 기존 시계 타이머가 날짜도 함께 갱신
- **하단 탭**: 좌측 사이드바 대신 **하단 네비게이션이 기본**. 등록된 메인 탭 수만큼 `UniformGrid Rows="1"`로 균등 분할, 각 칸은 아이콘(위) + 라벨(아래), 선택 시 상단 3px accent 바 + 옅은 accent 판
- **메인 컨텐츠**: 기존 `Margin="32"` 제거 — 영역 전체를 모듈 View가 사용. 셸은 컨텐츠 제목줄을 그리지 않음(선택된 하단 탭과 중복). 모듈이 없을 때는 사선 해치 브러시로 빈 슬롯 표시
- **아이콘**: Segoe Fluent 글리프 대신 **벡터 Geometry 24종**. `AddMain`의 `icon` 인자에 글리프가 아니라 아이콘 이름("Home", "Monitor" 등)을 넘김. 생략하면 라벨만 표시
- **모양 규칙**: 라운드 제거(서브탭 알약 → 각진 세그먼트, ChromeButton CornerRadius 0), 헤어라인 경계
- **색**: 라이트 = 바탕 #F2F2F3 / 판 #FFFFFF / accent #2196F3. 다크 = 바탕 #121317 / 판 #16171C / 경계 #2A2C33 / accent #22D3EE
- **폰트**: `Ubisam.Font.Heading` = "Barlow Condensed, Segoe UI", `Ubisam.Font.Body` = "Barlow, Segoe UI" (Barlow 미설치 시 Segoe UI 폴백)

## 3. 직접 수정해야 하는 기존 파일 2곳

### `src/UbisamBase.Core/Shell/ShellWindow.xaml.cs`

`ApplyNavPosition`에서 하단 바 높이를 100 → 72로 바꾸세요 (아이콘 + 라벨 두 줄 높이).

```csharp
NavList.Width = isHorizontal ? double.NaN : 140;
NavList.Height = isHorizontal ? 72 : double.NaN;
```

### `src/UbisamBase.Core/Settings/UiSettingsService.cs`

기본 네비게이션 위치를 하단으로 바꾸세요.

```csharp
[ObservableProperty]
private NavPosition navPosition = NavPosition.Bottom;
```

## 4. 탭 등록 예시 (`src/UbisamBase.App/AppSetup.cs`)

`icon` 인자는 이제 아이콘 이름입니다. 기존 등록에 이름을 채워 넣으세요.

```csharp
manager.AddMain<HomeView, HomeViewModel>(ViewIds.Home, "홈", "Home");
manager.AddMain<SettingsView, SettingsViewModel>(ViewIds.Settings, "설정", "Settings");
manager.AddSub<GeneralSettingsView, GeneralSettingsViewModel>(ViewIds.Settings, "일반");
```

사용 가능한 아이콘 이름 30종: Home, Monitor, Chart, Maintenance, Settings, Alarm, Log, Document, Data, Power, Temperature, Gauge, Run, Stop, Reset, Account, Lock, Export, Import, Search, Calendar, Clock, Link, Warning, Pass, Folder, Vision, Control, Recipe, Modules.

아이콘을 더 늘릴 때는 Lucide(https://lucide.dev)에서 **24×24 그리드 / 스트로크 1.5** 규칙으로 가져와 `Icons.xaml`에 `Geometry` 한 줄로 등록하세요. SVG의 `<circle>`/`<rect>`는 WPF Geometry 문법(호 `A` 두 개 / `M…L…Z`)으로 옮겨야 합니다.

## 5. 완료 후 확인할 것

1. 빌드가 통과하는지 (`dotnet build` 또는 Visual Studio)
2. `Icons.xaml`이 빌드에 포함되는지 — SDK 스타일 csproj + `UseWPF`라 자동 포함되지만, 리소스 조회 실패 시 `Page`로 명시 추가
3. 하단 탭이 창 폭에 균등 분할되고, 선택된 탭에 상단 accent 바가 보이는지
4. 설정 화면에서 테마를 Light/Dark로 바꿀 때 상단바·하단 탭·아이콘 색이 함께 전환되는지
5. 화면 배율(ChromeScale) 슬라이더를 움직였을 때 아이콘이 깨지지 않고 확대되는지
6. 아이콘 이름을 넘기지 않은 탭이 라벨만으로 정상 표시되는지

## 6. 하지 말 것

- 모듈 View(`HomeView`, `SettingsView`, `GeneralSettingsView` 등)의 내용은 건드리지 마세요 — 셸만 바꿉니다.
- 컨텐츠 영역에 제목/헤더를 다시 넣지 마세요.
- 기존 `TabManager`, `EventBus`, `ToastService`, `AuthService`, `LogService`의 구조나 시그니처를 바꾸지 마세요. `ShellViewModel`은 `Brand`/`CurrentDate` 추가 외에는 동일합니다.
