Supported Placeholders:

The block uses dynamic rendering to process placeholders on the frontend, ensuring your structured data always reflects current content.
Technical Details
The block uses a dynamic rendering approach with render_callback to process placeholders server-side. This ensures that:
- Placeholders are replaced with current data on every page load
- ACF fields are safely accessed and formatted
- Invalid JSON never reaches the frontend
- Search engines receive clean, valid JSON-LD markup
The frontend output is optimized with no extra paragraph or break tags, outputting only the pure JSON-LD script tag.
