close #149 후속

작업 내용

  • SajuCard 잘림 수정(SajuCard 잘림 현상 수정 #149) 이후, 고정 폭(48dp)으로 쓰이는 만세력 화면(SajuFourPillarsTable)에서 여전히 텍스트가 잘리는 것을 확인하여 재작업

변경사항 / 상세

  • Figma 노드(48dp 카드, hanja 18sp/lineHeight 26 · reading 10sp/lineHeight 13) 실측을 기준으로, BoxWithConstraints로 읽은 카드 실제 폭에 비례해 두 텍스트의 폰트 크기가 함께 커지고 작아지도록 변경(HANJA_FONT_SIZE_RATIO/READING_FONT_SIZE_RATIO = 48dp 기준 비율)
  • 카드는 aspectRatio(1f)로 항상 정사각형 유지
  • 두 텍스트 사이 간격을 고정값이 아니라 (카드 내부 가용 높이 - lineHeight 합)으로 매번 계산해서, 폭이 아무리 좁아져도(또는 시스템 글자 크기가 커져도) 텍스트가 절대 잘리지 않도록 처리
  • SajuCardScalingPreview 프리뷰 추가(32~120dp 폭별 비교)

중점 리뷰사항

  • HANJA_FONT_SIZE_RATIO/READING_FONT_SIZE_RATIO 계산 기준(48dp 카드)이 다른 화면(SajuPaljaGrid, weight 기반 가변 폭)에서도 시각적으로 자연스러운지 확인 부탁드립니다

Summary by CodeRabbit

  • 개선
    • 카드 너비에 맞춰 텍스트 크기와 줄 간격이 자동으로 조정됩니다.
    • 좁은 카드에서도 콘텐츠가 더 자연스럽게 표시되도록 내부 여백과 배치가 개선되었습니다.
    • 다양한 카드 너비에서의 표시 품질을 확인할 수 있도록 미리보기가 추가되었습니다.

카드 폭이 48dp 이하이거나 시스템 글자 크기가 커지면 두 텍스트의 간격이 음수가 되어 서로 겹칠 수 있습니다. 좁은 만세력 카드에서 가독성이 손상될 수 있으므로 병합 전에 간격 계산을 보정해야 합니다.

AndroidX Compose Arrangement.spacedBy negative space official documentation

💡 Result:

Yes, using a negative value in AndroidX Compose's Arrangement.spacedBy is an officially supported use case [1][2]. According to the official Android documentation, passing a negative value to Arrangement.spacedBy causes the children within the layout (such as Row or Column) to overlap [3][4]. This works because the negative spacing is subtracted from the available space that the children can occupy [3][5]. Key points regarding this functionality: - Supported layouts: It is supported across standard layouts as well as Lazy lists and grids [1][2]. - Effect: The items will overlap by the specified negative distance [3][4]. - Implementation: You can use it as shown in the following example: Row(horizontalArrangement = Arrangement.spacedBy(-20.dp)) {... } [6] This capability allows for stacking effects or custom overlapping UI patterns [1][2].

[P1] 음수 lineGap으로 텍스트가 겹치지 않도록 수정하세요.

48dp 카드에서 availableHeight는 36dp이고 contentHeight는 39dp이므로 lineGap은 -3dp입니다. 32dp 카드에서는 -6dp이며, 시스템 글자 크기가 커지면 겹침이 더 커집니다. 글자 크기를 가용 높이에 맞춘 뒤 lineGap을 0dp 이상으로 계산하세요.
