@gullabs/flipbook-core 3.2.1 + Hopepilled lower-corner clipping patch
Copyright (c) 2026 Gul Labs. Includes StPageFlip by Nodlik (MIT).
Core license: MPL-2.0. Full MPL and upstream MIT notice: LICENSE.txt.

Modification: include the side-edge intersection when a lower-corner fold
has not crossed the top edge. Otherwise the revealed page's clipping polygon
has only two vertices and disappears. Decorative fold copies also remove media
sources before insertion, so a MediaSource blob is never attached twice.
The ESM entry point re-exports the same public runtime API as upstream.
Rebuilt with esbuild 0.27.4 (MIT), an existing local build tool.
