Demos

Lightweight interactive experiments to illustrate movable book behaviors—no full IIIF viewer required.

• Fold crossfade slider

• Fold flip (manifest-driven)

  Animate a circular flap flipping using hinge and region data parsed from the local IIIF manifest.

• Recto–Verso flip (Imperiia 315)
