Block nesting now supports up to 3 levels deep.

Before: Limited to 2 levels.

Now: Build richer content hierarchies:

Page > Section > Grid > Card

Features:

• Single request - Fetch API resolves all nested levels at once

• Configurable depth - Set maximum nesting per block type

• Improved UI - Better navigation with collapsible sections

This addresses feedback from teams building component libraries where 2 levels proved limiting for realistic design patterns. Performance remains optimal through efficient query batching.
