Synced patterns always store in the database and insert as references rather than embedded content. The editor shows a block reference with the pattern’s database post ID.
All changes to synced patterns sync everywhere they’re used – content updates, style changes, and structural modifications apply to every instance automatically.
This makes synced patterns powerful for maintaining consistency across your site. Update the pattern once and see changes everywhere it appears.
The trade-off is database dependency and inability to customize individual instances. Synced patterns work best for components that should always look and behave identically.
