When lang=en is used left to right AND top to bottom

Hello,

For your advice please.

I'm looking at a design where the text of a page reads left to right in the main. Additionally text as legible characters also 'read' from the top down, the characters bottom margin runs down. This text is for affect yet is proposed in a fashion where they can be read, if with difficulty for some.

Is there a criterion for A, AA or research that shows this design should not be used if AA is to be approached?

I have commented that they should not be text as an image using WCAG 2.1, 1.4.5<https://www.w3.org/WAI/WCAG21/Understanding/images-of-text.html> and I understand that 1.3.4 Orientation isn't intended for this design<https://www.w3.org/TR/WCAG21/#orientation>. The archives haven't shown much related to orientation or sideways search terms.

Thanks in advance,


Chris.
