IIIF Deep-Zoom Before/After Block

This block is purpose-built for galleries, museums, restoration projects, cartography, and microscopy. Paste two IIIF endpoints (either Image API info.json or manifests v2/v3) and get a deep-zoom comparison with lockstep pan/zoom.

Features * Synchronized pan/zoom using OpenSeadragon (bundled, BSD-3-Clause) * Accepts IIIF Image API info.json or IIIF Manifests (v2/v3) * Draggable reveal slider + accessible range input * Labels (e.g., "Before" / "After"), start position, and optional badges * Align wide/full support; server-side render with sanitized output * No tracking, no external calls beyond the IIIF URLs you provide
