Class LayoutEngine

java.lang.Object

io.leandev.appfuse.report.internal.layout.LayoutEngine

public final class LayoutEngine
extends Object

排版引擎：把 ReportDocument 排成逐頁的定位 box，交給 PageSink

只依賴 TextMeasurer 與 ImageInspector，不依賴 PDF 實作。規則見 REP-03 契約設計： 孤行寡行的四個步驟、keepWithNext、KeepTogether、表格（TablePlacer）、圖形（GraphicLayout）、 頁首頁尾（RegionLayout），以及「自動換頁後同一內容仍放不下即停止」的前進保證。
