Description of Changes

Before

• CSS build included automatic Pretendard font loading via tsup banner configuration
• Font was automatically imported in generated CSS files: @import url("https://cdn.jsdelivr.net/gh/orioncactus/pretendard@v1.3.9/dist/web/variable/pretendardvariable-dynamic-subset.min.css");

After

• Removed banner.css option from tsup config in packages/core/tsup.config.ts:138-141
• Font loading is now the responsibility of the consuming application
• Applications must manually include Pretendard or their preferred font

Rationale

1. Flexibility: Applications can choose their preferred font loading strategy (CDN, self-hosted, variable fonts, etc.)
2. Performance: Avoids duplicate font loading when applications already have font management
3. Industry Standard: Aligns with how other major design systems handle typography
4. Control: Gives applications full control over font loading timing and fallbacks

Summary of Changes

Hello @ZeroChoi2781, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

이 PR은 CSS 빌드 프로세스에서 Pretendard 폰트의 자동 로딩 기능을 제거하여, 애플리케이션이 폰트 로딩을 직접 관리할 수 있도록 변경합니다. 이는 폰트 로딩 전략에 대한 유연성을 높이고, 잠재적인 중복 로딩을 방지하여 성능을 개선하며, 업계 표준에 맞춰 애플리케이션에 더 많은 제어권을 부여하는 것을 목표로 합니다.

Highlights

• CSS 빌드에서 폰트 로딩 제거: tsup 빌드 설정에서 Pretendard 폰트의 자동 로딩을 제거했습니다. 이제 폰트 로딩은 애플리케이션의 책임이 됩니다.
• 폰트 로딩 유연성 증가: 애플리케이션이 자체적으로 폰트 로딩 전략을 선택할 수 있도록 하여 유연성을 높였습니다.
• 성능 및 제어 개선: 중복 폰트 로딩을 방지하고, 폰트 로딩 타이밍 및 폴백에 대한 완전한 제어를 제공하여 성능을 향상시킵니다.

Code Review

안녕하세요. PR을 잘 검토했습니다. tsup 설정에서 Pretendard 폰트 자동 로딩 기능을 제거하여 라이브러리 사용자가 폰트 전략을 직접 관리하도록 변경한 점은 유연성 측면에서 좋은 결정입니다. 다만, 이 변경은 사용자에게 영향을 미치는 파괴적인 변경(Breaking Change)이므로, Conventional Commits 명세에 따라 이를 명확히 표시할 필요가 있습니다. 관련하여 packages/core/tsup.config.ts 파일에 구체적인 리뷰 의견을 남겼으니 확인 부탁드립니다.
