📖 Digital Book — Embed, PDF & Image Gallery Blocks

What's included:

✅ Embed block — Drop in any YouTube, Vimeo, or iframe-able URL. Auto-detects YouTube/Vimeo and embeds them with the proper player. Use it for property walkthroughs, training videos, demo reels, or any external embed.

✅ PDF block — Pick a PDF from your File Manager. Renders inline with a Download button. No need to link out to a separate PDF QR — welcome guides, menus, manuals, and contracts now live inside the book.

✅ Image Gallery block — Multi-image grid in 1, 2, or 3 columns. Lazy-loaded so pages stay fast even with 20+ photos. Add, remove, and reorder anytime.

✅ Slash menu access — Type "/" inside any Digital Book page to bring up all blocks (now 21 in total) and pick the one you need.

✅ Real-time preview — Changes to embed URLs, PDFs, or gallery images update in the editor instantly, so you see exactly what visitors will see.

Existing Digital Books are not affected — these blocks only appear if you add them.

Try it: Create/Edit any Digital Book QR → open a page → type "/" → pick Embed, PDF, or Image Gallery.
