Interface RawNode

escape hatch (level 2) — the user draws with jsPDF directly, while the engine still manages the cursor/page-break: measure(contentWidth) reports the height up front so the engine can decide whether to break before drawing, then draw gets the exact position + width to render at

interface RawNode {
    draw: (doc: jsPDF, cursor: RawDrawCursor) => void;
    measure: (contentWidth: number) => number;
    type: "raw";
}
