Accumulator-based renderer, similar to foldl.

• init: Starting accumulator value
• tagged: Handle tagged text (for syntax highlighting)
• untagged: Handle untagged text and indentation
• newline: Handle line breaks (add \n here if needed)
• outer: Transform final accumulator to output type

Text is processed left-to-right; reverse lists if accumulating in order.

htmlRenderer : Renderer Tag (List (Html msg)) (Html msg)
htmlRenderer =
    { init = []
    , tagged = \tag text acc -> styledSpan tag text :: acc
    , untagged = \text acc -> Html.text text :: acc
    , newline = \acc -> Html.br [] [] :: acc
    , outer = \acc -> Html.pre [] (List.reverse acc)
    }

Renders a document using a custom Renderer.

Pretty prints with both page width and ribbon width constraints.

The ribbon width limits non-indentation characters per line. At indentation level i, the effective width is min(pageWidth, i + ribbonWidth).
