   The legacy pdf.min.mjs and pdf.worker.min.mjs bundles are renamed to .js to support

   Copyright (c) 2020 Nodlik.
   License: MIT. See assets/vendor/page-flip/LICENSE.
   Local modification by 建站阿来 (2026-10-19): store and cancel the animation-frame
   request and stop rendering when PageFlip.destroy() is called. This prevents
   abandoned rendering loops when rebuilding for responsive sizes and zoom levels.
   No other vendor behavior is intentionally changed.

3. Demonstration publications
   Created for this plugin. Fictional sample content and original vector graphics.
   No materials or assets from the Real3D FlipBook commercial product are included.
