Upload an EPUB, read it directly in the browser, adjust the type size, and keep footnotes in calm popovers instead of dumping readers into back matter.
This EPUB reader demo is intentionally local-only right now. Reader-state persistence will move to Cloudflare-backed sync once the Reader State DB is bound.
This environment is missing Cloudflare resources the current route family expects before launch.
