1.4.10: Reflow exception for an interactive e-book

Hello,

The web e-book I am building has a two-dimensional layout (book pages) built on HTML5 canvas that contains interactive elements such as paragraphs, words, illustrations etc. It was purposefully designed to be navigated as a book, where you can leaf through the pages like a physical book. So, I found shrinking the content to 320px irrelevant in this case. I am wondering if this falls under Reflow exception ?

IF NO - The product is built for Desktop usage, for Mobile/Tablet use there is a separate app available in epub format. I can link it from the default website. Can this be considered as alternative conforming version like in this case<https://www.w3.org/WAI/WCAG21/Understanding/reflow.html#responsive-web-design-and-other-ways-to-meet-this-success-criterion> ?
Thank you,
Hayk
