fix(sms-permission): re-request on denial and guide permanent denial to app settings

Summary: Improve SMS permission UX so users can request again after denial and are guided to app settings when permanently denied.\nChanges: handle Permission.sms status in controllers, show settings dialog for permanently denied, use kIsWeb guard, context-safety across async.\nValidation: scripts/check.sh passed (analyze/tests OK).\nRisk & Rollback: low; scoped to permission request flow. Revert two controllers if issues.

+Use AGENTS.md at repo root as the source of truth for coding rules and guardrails.
+
+Key Rules
+- Code first, concise rationale after. If uncertain, say "Uncertain:".
+- Keep diffs minimal; follow existing patterns and `analysis_options.yaml`.
+- Validate with `scripts/check.sh` (format/analyze/test) before completion.
+- Ask for approval before dependency changes, build config edits, or network access.
+
+Templates
+- Task and PR templates are in `AGENTS.md` and `doc/agents/codex_prompt_templates.md`.

+
+Scope
+- Applies to the entire repository unless a more specific rule exists deeper in the tree.
+- Precedence: project AGENTS.md > project .claude/agents > user ~/.claude > default Codex CLI rules. Direct system/developer instructions always win.
+
+Goals
+- Accelerate small, safe changes with consistent quality.
+- Keep diffs minimal, focused, and aligned with Flutter best practices.
+
+Guardrails
+- Workspace only: modify files within this repo. Ask before adding dependencies or using network.
+- Safety: avoid destructive actions (file deletions, rewrites, config changes) unless explicitly requested.
+- Responses: be concise; code first, short rationale after. If uncertain, prefix with "Uncertain:". If multiple viable solutions, show the top 2 briefly.
+- Planning: for multi‑step tasks, maintain an update_plan with exactly one in_progress step.
+- Language: 기본적으로 한국어로 응답합니다. (필요 시 코드/로그/명령어는 원문 유지)
+
+Coding Standards
+- Language: Dart/Flutter (SDK >= 3.0). Respect `analysis_options.yaml` (flutter_lints baseline).
+- Style/format: use `dart format .` and keep changes minimal. Avoid one‑letter variable names; avoid inline comments unless requested.
+- Structure: follow existing file/module patterns and naming. Do not introduce new frameworks or architectural shifts without approval.
+- Tests: add or update tests when behavior changes or bugs are fixed (if feasible). Keep tests scoped to the change.
+
+Validation
+- Always run local checks via `scripts/check.sh` before proposing completion:
+  - formatting check: `dart format --set-exit-if-changed .`
+  - static analysis: `flutter analyze`
+  - unit/widget tests: `flutter test` (ok if none exist)
+- UI changes: include brief description of visual impact; screenshots if readily available by the user.
+
+Sensitive Areas (require explicit approval)
+- Android/iOS/macOS build configs, signing, bundle identifiers, Gradle/Kotlin/Swift project settings.
+- Dependency graph changes (pubspec.yaml add/remove/upgrade).
+- Network access, calling external APIs, or adding secrets.
+
+Operational Conventions
+- Branch naming: `codex/<type>-<slug>` (e.g., `codex/fix-url-matcher`).
+- Commits: Conventional Commits preferred (e.g., `fix: correct url matching for X`).
+- PR description template:
+  - Summary: what/why

+# AdMob 미디에이션 네이티브 광고 네트워크 (Android)
+
+아래 네트워크들은 AdMob 미디에이션을 통해 Android에서 네이티브(Native) 광고를 지원합니다. 실제 지원 범위(포맷/통합 방식)는 지역/계정/버전 등에 따라 달라질 수 있으므로 AdMob 콘솔에서 해당 미디에이션 그룹의 포맷 선택 가능 여부로 최종 확인하세요.
+
+## 권장 후보
+- Meta Audience Network (FAN)
+  - 통합: Bidding 전용
+  - 포맷: Native, Native Banner
+  - 문서: https://developers.google.com/admob/android/mediation/meta
+- InMobi
+  - 통합: Waterfall(네이티브는 Waterfall만), Bidding(다른 포맷)
+  - 포맷: Native

+
+## 참고 및 주의사항
+- 지역성/수요: Pangle(아시아), LINE(일본), myTarget(RU/CIS) 등은 지역별 수요 차이가 큼. 타겟 지역 기준으로 우선순위 구성 권장.
+- 통합 방식: 일부는 네이티브가 Waterfall만 지원(InMobi, ironSource), 일부는 Bidding만(Meta), 혼합 지원(Pangle, Mintegral, Unity). 비딩/워터폴 여부에 따라 콘솔 설정이 상이함.
+- SDK/어댑터: Android Gradle에 각 네트워크 SDK/어댑터 추가가 필요하며, AdMob UI에서 해당 네트워크를 미디에이션 그룹의 “Native” 포맷으로 매핑해야 함. 개인정보/동의 메시징(US State Privacy, GDPR 등)도 파트너 추가 필요.
+- 템플릿/표시: 대부분 Unified Native 기반 에셋을 제공하나 네트워크별 에셋 세트가 달라 `NativeTemplateStyle` 기반 템플릿 레이아웃 조정이 필요할 수 있음.
+- AppLovin 유의: 문서상 포맷 표에 Native가 보이더라도 어댑터 변경 이력에 “Native 지원 제거”가 기록되어 있습니다. 실제 지원은 AdMob 콘솔(미디에이션 그룹)에서 포맷 선택 가능 여부로 재확인하세요. 문서: https://developers.google.com/admob/android/mediation/applovin
+- Flutter 연동: `google_mobile_ads`의 `NativeAd` 로드/리스너/`AdWidget` 사용 패턴은 동일. 네트워크 추가는 네이티브(Android) 쪽 SDK/어댑터 및 콘솔 설정이 핵심.
+
+## 빠른 적용 체크리스트
+- [ ] 타겟 지역에 맞는 네트워크 선정(2~5개)
+- [ ] Android 의존성 추가(네트워크 SDK/어댑터)
+- [ ] AdMob 콘솔: 미디에이션 그룹 생성(포맷=Native), 각 네트워크 매핑
+- [ ] 테스트 모드/테스트 광고 확인(네트워크별 테스트 설정 있음)
+- [ ] 앱 내 네이티브 광고 UI 검수(템플릿/에셋 배치, 정책 준수)
+
+---
+
+## 지역별 우선순위 제안(예시)
+아래는 일반적인 트래픽·수요 기준의 스타트 세트 예시입니다. 실제 퍼포먼스는 앱 카테고리/유저 페르소나/국가별 규제에 따라 달라질 수 있으므로 A/B로 조합을 검증하세요.
+
+- 한국/일본(KR/JP)
+  - 1군: Meta(FAN, Bidding) + Pangle(Bidding/Waterfall) + LINE(JP, Bidding/Closed Beta for Native)
+  - 보강: Mintegral, InMobi, Unity
+- 북미/유럽(NA/EU)
+  - 1군: Meta(FAN) + InMobi + Unity + Chartboost
+  - 보강: DT Exchange(Fyber), Moloco
+- 동남아/인도(SEA/IN)
+  - 1군: InMobi + Pangle + Mintegral + Meta(FAN)
+  - 보강: Unity, DT Exchange
+- CIS/러시아권
+  - 1군: myTarget
+  - 보강: Mintegral, Unity
+
+참고: Chartboost는 네이티브 포맷 지원. 지역/장르에 따라 성과 편차가 있어 NA/EU 게임 카테고리에서 보강용으로 고려.

+
+## Android Gradle 의존성(예시)
+Flutter에서 `google_mobile_ads`를 사용해도, 미디에이션 파트너의 Android SDK/어댑터는 Gradle에 직접 추가해야 합니다. 아래 스니펫은 예시이며, “정확한 최신 버전”은 각 네트워크 문서의 Adapter 섹션(Changelog/Artifacts)에서 확인 후 고정하세요.
+
+프로젝트 수준 `settings.gradle`/리포지토리 설정은 기본 `google()`/`mavenCentral()`이면 충분합니다.
+
+`android/app/build.gradle` (dependencies 블록)
+
+```gradle
+dependencies {
+    // Google Mobile Ads SDK (보통 어댑터가 transitive로 끌어오지만 명시해도 무방)
+    implementation 'com.google.android.gms:play-services-ads:24.6.0' // 최신 권장 버전으로 교체
+
+    // Mediation adapters (예시 버전; 실제 최신 버전으로 교체)
+    implementation 'com.google.ads.mediation:facebook:6.16.0.0'      // Meta Audience Network
+    implementation 'com.google.ads.mediation:pangle:5.5.0.4.0'       // Pangle
+    implementation 'com.google.ads.mediation:mintegral:16.5.91.1'    // Mintegral
+    implementation 'com.google.ads.mediation:inmobi:10.6.3.0'        // InMobi
+    implementation 'com.google.ads.mediation:fyber:8.3.8.0'          // DT Exchange(Fyber)
+    implementation 'com.google.ads.mediation:moloco:3.8.0.0'         // Moloco
+    implementation 'com.google.ads.mediation:ironsource:8.5.0.1'     // ironSource
+    implementation 'com.google.ads.mediation:unity:4.16.0.1'         // Unity Ads
+    implementation 'com.google.ads.mediation:mytarget:5.20.0.0'      // myTarget
+    // implementation 'com.google.ads.mediation:chartboost:<version>' // Chartboost (필요 시)
+}
+```
+
+버전 확인 팁:
+- 각 네트워크 가이드의 “Supported integrations and ad formats”/“Changelog”에서 최소/최신 어댑터 버전 확인
+- Maven Central에서 `com.google.ads.mediation:<artifact>` 검색하여 최신 릴리스 확인
+- AdMob 콘솔에서 해당 네트워크 추가 시 표시되는 가이드/버전 주석 참조
+
+설정 체크:
+- ProGuard/R8 규칙이 필요한 네트워크의 경우 가이드에 명시된 keep 규칙 추가
+- COPPA/유럽·미국 주 개인정보법 관련 consent 전달(UMP SDK 또는 자체 메시징) 및 파트너 동기화
+- 테스트: 네트워크 콘솔에서 테스트 모드 또는 테스트 디바이스 ID 설정 후 실제 단말에서 `NativeAd` 로드 확인

+# SubManager UI 리디자인/리팩터링 계획 (flutter-shadcn-ui 기반)
+
+## 개요
+- 목적: 앱 전반 UI를 `flutter-shadcn-ui`로 표준화하고, 라이트/다크 테마와 의미 있는 컬러 체계를 구축. 사용하지 않는 코드/파일 정리, 복잡한 알고리즘을 동등 효과의 단순한 구현으로 교체.
+- 원칙: 색채심리학/게슈탈트 심리학/피츠의 법칙/마이크로인터랙션을 반영. 화면 간 일관성 유지. 사이드 이펙트 최소화(동작/데이터 모델 변경 없이 UI 중심).
+- 범위: `lib/screens`, `lib/widgets`, `lib/theme` 전반. 일부 `services/*` 단순화 대상 포함(동일 기능 유지).
+
+## 사전 승인 필요(착수 전)
+1) 의존성 추가: `flutter_shadcn_ui` (pubspec.yaml).  
+2) 테마 구조 재구성: 기존 `app_theme.dart`, `app_colors.dart` → shadcn 토큰/스케일 중심으로 정리.  
+3) 불용 파일 삭제: 기존 커스텀 위젯·스타일(예: 글라스모피즘 계열 등) 제거.  
+4) 점진적 마이그레이션 방식 선택(권장) 또는 일괄 치환(위험도 높음).
+
+## 접근 전략(옵션)
+- 옵션 A: 점진적 이행(권장)  
+  1단계 토대(테마/토큰/기본 컴포넌트) → 2단계 주요 화면 치환 → 3단계 잔여 위젯/정리. 리스크 낮고 롤백 용이.
+- 옵션 B: 일괄 치환  
+  모든 화면/컴포넌트를 한 번에 교체. 속도는 빠르나 충돌/리스크 큼. 권장하지 않음.
+
+이 계획서는 옵션 A를 기준으로 작성합니다.
+
+## 테마·컬러 설계
+- 토큰: primary, secondary, success, warning, danger, info, background, foreground, muted, accent, border, card, popover, ring, overlay.
+- 라이트/다크 지원: 동일 의미 색상(semantics)을 양 테마에 매핑. 최소 WCAG 4.5:1 대비.
+- 색채심리학 반영(과장 금지, 절제된 사용):  
+  - info: 블루(신뢰/안정),  
+  - success: 그린(완료/안도),  
+  - warning: 앰버(주의 환기),  
+  - danger: 레드(중단/삭제),  
+  - neutral: 슬레이트/징크 계열(콘텐츠 중심).  
+- 게슈탈트: 시각적 그룹화(카드/섹션/간격 체계), 시선 흐름(타이포·계층), 근접성·유사성 활용.
+- 피츠의 법칙: 주요 액션 버튼 터치 타깃 ≥ 44dp, 간격 여유.
+- 마이크로인터랙션: 진입/전환 120–200ms, 물리 기반 커브, Reduced Motion 설정 반영(`utils/reduce_motion.dart` 유지/연동).
+
+구현 포인트(코드 단계에서 적용):
+- `ShadcnTheme` 확장 혹은 테마 브리지 레이어 생성(예: `lib/theme/shadcn_theme.dart`) 후 기존 `ThemeData`와 연결.
+- `TextTheme`/`ColorScheme`를 shadcn 토큰으로 역매핑해 타 3rd-party 위젯과도 일관성 유지.
+
+## 컴포넌트 매핑(현행 → shadcn)
+- 버튼: `common/buttons/(primary|secondary)_button.dart` → `Button(variant: primary/secondary)`
+- 카드: 다수의 카드형 위젯 → `Card` + `CardHeader/Content/Footer`
+- 다이얼로그: `dialogs/*` → `Dialog`/`AlertDialog` + 의미 색상(위험=red)
+- 스낵바: `app_snackbar.dart` → `Toast` 또는 `Inline Alert`(상황별)
+- 입력: `base_text_field.dart`, `currency_input_field.dart`, `date_picker_field.dart`, `selector`류 → `Input`, `Select`, `Popover+Calendar`(날짜)
+- 네비게이션: `floating_navigation_bar.dart` → shadcn 스타일 버튼/탭/세그먼트 조합(기능은 Navigator 유지)
+- 리스트/아이템: `subscription_*_card(_widget).dart` → `Card`+`List` 조합, 의미 색상 배지 사용
+- 배지/상태: `analysis_badge.dart` → `Badge`(success/warning/info)
+
+차트는 기존 라이브러리 유지, `Card`/토큰 색상만 적용.
+
+## 화면별 리디자인 가이드
+- 메인(`main_screen.dart`): 상단 요약(카드), 탭형 네비게이션, FAB 대신 우선작업 배치(피츠 법칙 반영).
+- 구독 추가(`add_subscription_screen.dart`): 단계적 폼(섹션 카드), 필수/보조 액션 분리, 에러/힌트 색상 표준화.
+- 상세(`detail_screen.dart`): 정보/행동 분리, 위험 액션은 `danger` 톤, url 영역은 `info` 톤.
+- 분석(`analysis_screen.dart`): KPI 카드 3열(태블릿), 1열(폰), 차트 색상은 의미 기반 팔레트.
+- 카테고리 관리(`category_management_screen.dart`): 리스트+인라인 편집, 확인/취소 분리, 경고 색상 남용 금지.
+- 설정(`settings_screen.dart`): 토글/셀리스트 일관, 테마 전환 즉시 반영, 접근성 강조.
+- SMS 권한(`sms_permission_screen.dart`): 단일 초점 화면, primary 호출-행동 버튼 + 보조 링크.
+- 스플래시/잠금: 단순한 브랜드/배경, 과도한 애니메이션 제거.
+
+## 정리/삭제 대상(마이그레이션 완료 후)
+- 강한 시각효과 위젯: `animated_wave_background.dart`, `glassmorphism_card.dart`, `glassmorphic_scaffold.dart` 등
+- 중복/대체 가능: 커스텀 버튼/카드/스낵바/다이얼로그 구현체(치환 완료 후)
+- 사용되지 않는 유틸: 실사용 참조 0인 파일 전부
+- 임시/백업: 오래된 백업/실험 파일
+
+삭제는 단계별 PR에서 “치환 완료 확인 → 삭제” 순으로 안전하게 진행.
+
+## 알고리즘 단순화(동일 효과 유지)
+- SMS 스캔(`services/sms_scanner.dart`): 필터→파서→정규화 단일 파이프라인(순수 함수)로 재구성, 캐시/메모리 최적화 과잉 제거.
+- URL 매처(`services/url_matcher/*`): 정규식 테이블 기반 단일 매칭기로 단순화(사전컴파일 RegExp), 서비스 데이터는 레포지토리 1곳에서 주입.
+- 환율(`exchange_rate_service.dart`): `CacheManager` TTL 캐시 단일 책임, 만료 시 새로고침. 중복 포맷터/파서 제거.
+- 알림(`notification_service.dart`): 스케줄/권한 체크를 단일 파사드로 노출, 내부 분기 축소.
+- 성능 유틸(`performance_optimizer.dart`, `memory_manager.dart`): 체감·유지보수 이점 낮은 미세 최적화 제거, 프레임 드랍 유발 가능 애니메이션 단순화.
+
+모든 변경은 퍼블릭 API/데이터 모델을 유지해 사이드 이펙트 방지.
+
+## 테스트/검증
+- 스크립트: `scripts/check.sh` 전 단계 실행(포맷/분석/테스트). 기존 deprecation 경고는 별 PR로 정리.
+- 위젯/골든 테스트: 핵심 화면(메인/추가/상세/분석/설정) 라이트/다크 2종 캡처 비교.
+- 유닛 테스트: URL 매처/환율 캐시/SMS 파이프라인.
+- 접근성: 대비·포커스·터치 타깃 수동 점검 체크리스트.
+
+## 작업 단위/PR 계획
+1) 토대 구축: 의존성 추가 + 테마 브리지 + 핵심 컴포넌트(Button/Input/Card/Dialog) 도입.  
+2) 공용 UI 치환: 스낵바/다이얼로그/폼 필드/카드 템플릿 적용.  
+3) 화면별 리디자인: 메인→추가→상세→분석→설정 순.  
+4) 불용 코드 삭제: 치환 완료 파일 제거.  
+5) 알고리즘 단순화: sms/url/환율/알림 순으로 단일화 + 테스트.  
+6) 마감: 디테일 조정/접근성/성능 점검.
+
+- 브랜치: `codex/feat-shadcn-migration-*` (단계별).  
+- 커밋: Conventional Commits + 한국어 본문.  
+- 롤백: 각 단계는 기능 플래그/치환 전후 비교가 쉬운 최소 단위로 유지.
+
+## 위험 및 완화
+- 리소스 색상/테마 충돌 → 토큰 브리지로 양방향 매핑, 미호환 위젯은 유지.  
+- 3rd-party 차트/네이티브 UI → 표면 색/텍스트만 토큰 적용.  
+- 분석 실패(deprecation) → 별 PR로 API 교체(`activeColor` 등), 마이그레이션과 분리 처리.
+
+## 승인 체크리스트(Yes/No)
+- [ ] `flutter_shadcn_ui` 의존성 추가 승인이 필요합니다.  
+- [ ] 테마 구조(shadcn 토큰 중심) 재구성 승인.  
+- [ ] 단계별 불용 파일 삭제 승인.  
+- [ ] 점진적 이행(옵션 A)로 진행 승인.
+
+## 완료 기준(각 단계)
+- `scripts/check.sh` 무사 통과(분석 경고 해결 내역은 별 PR 또는 병행).  
+- 라이트/다크 스냅샷 비교 이상 없음.  
+- 대상 화면/컴포넌트 치환 100% 및 구식 코드 제거.
+
+---
+작성자 메모: 본 계획은 코드 변경 없이 문서만 추가되었습니다. 승인 후 단계별 구현을 진행합니다.
