MarkdownColors
class MarkdownColors(val text: Color, val codeBackground: Color, val inlineCodeBackground: Color, val dividerColor: Color, val tableBackground: Color, val alert: MarkdownAlertColors)
The colours MarkdownAguiTextRenderer draws with.
Five colours plus the GFM alert set. text is the one a caller actually knows; the other four are backgrounds and rules that only have to read against the surface behind the transcript, which is why markdownAguiColors derives them from text rather than asking for each.
