Gets or sets a dictionary mapping custom markup style tokens (e.g. primary, success) to styles.
[Nullable(new byte[] { (byte)2, (byte)1 })]
public Dictionary<string, AnsiStyle>? MarkupStyles { get; set; }
This dictionary is used by WriteMarkup(String) and related methods to resolve custom markup tokens.
If you mutate the dictionary in-place, call NotifyMarkupStylesChanged() so cached markup renderers can be rebuilt. Alternatively, update styles via SetMarkupStyle(String, AnsiStyle) which invalidates automatically.
