For now, Sasabune*** style only works on MarkdownScrollViewer.
And It don't references FlowDocument properties but MarkdownScrollViewer properties.

Markdown engine = new();
FlowDocument document = engine.Transform("# Heading1\n## Heading2\n### Heading3\n#### Heading3\nfoo bar text\n|head1|head2|\n|-|-|\n|body1|body2|");
document.Style = MarkdownStyle.SasabuneStandard;

// MarkdownScrollViewer MSV = new();
MSV.Document = document;
MSV.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
MSV.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

as soon, I have style, Header 1 2 3 don't work anymore for me,
only R0C0 with no style ( style in Xaml, but don't work header is not red or blue ).

`
Markdown engine = new();

        //string markdownTxt = "";
        string markdownTxt = "# Heading1\n## Heading2\n### Heading3\n#### Heading3\nfoo bar text\n|head1|head2|\n|-|-|\n|body1|body2|";
        //string markdownTxt = System.IO.File.ReadAllText("example.md");
        FlowDocument document1 = engine.Transform("# Heading1\n## Heading2\n# 1-R0C0 Style XAML\n" + markdownTxt);
        FlowDocument document2 = engine.Transform("# Heading1\n## Heading2\n# 2-R1C0 Sasabune\n" + markdownTxt);
        FlowDocument document3 = engine.Transform("# Heading1\n## Heading2\n# 3-R0C1 SasabuneCompact\n" + markdownTxt);
        FlowDocument document4 = engine.Transform("# Heading1\n## Heading2\n# 4-R1C1 SasabuneStandard\n" + markdownTxt);


        // Document.Style = MarkdownStyle.Sasabune;  ( style in xaml )
        MSV_R0C0.Document = document1;
        MSV_R0C0.Document.Background = new SolidColorBrush( Color.FromArgb(255, 0, 0, 0)); // a,r,g,b
        MSV_R0C0.Document.Foreground = new SolidColorBrush( Color.FromArgb(255, 255, 255,255));


        
        document2.Style = MarkdownStyle.Sasabune;
        MSV_R1C0.Document = document2;
        MSV_R1C0.Document.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
        MSV_R1C0.Document.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

        document3.Style = MarkdownStyle.SasabuneCompact;
        MSV_R0C1.Document = document3;
        MSV_R0C1.Document.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
        MSV_R0C1.Document.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

        document4.Style = MarkdownStyle.SasabuneStandard;
        MSV_R1C1.Document = document4;
        MSV_R1C1.Document.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
        MSV_R1C1.Document.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

Please modify your code as the bellow.

MSV_R0C0.Document = document1;
MSV_R0C0.Background = new SolidColorBrush( Color.FromArgb(255, 0, 0, 0)); // a,r,g,b
MSV_R0C0.Foreground = new SolidColorBrush( Color.FromArgb(255, 255, 255,255));

document2.Style = MarkdownStyle.Sasabune;
MSV_R1C0.Document = document2;
MSV_R1C0.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
MSV_R1C0.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

document3.Style = MarkdownStyle.SasabuneCompact;
MSV_R0C1.Document = document3;
MSV_R0C1.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
MSV_R0C1.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

document4.Style = MarkdownStyle.SasabuneStandard;
MSV_R1C1.Document = document4;
MSV_R1C1.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));
MSV_R1C1.Foreground = new SolidColorBrush(Color.FromArgb(255, 255, 255, 255));

Sasabune***(Sasabune, SasabuneCompact and SasabuneStandard) refers only to the direct properties of MarkdownScrollViewer.

merci @whistyun
Yes it's work fine, sorry I don't see in your first post, the subtle difference between set at document level vs set at Viewer level.
Have a good day.
