CMS Layout Section Caching

Multi-layer caching strategy for layout sections (Header, Footer, Theme, etc.) across @decocms/blocks and @decocms/tanstack. These sections appear on every page but rarely change — caching them eliminates the biggest source of redundant API calls.

When to Use This Skill

• Server logs show repeated intelligent-search/product_search calls for Header shelves on every navigation
• Variant changes trigger full CMS resolution including Header/Footer
• [CMS] logs show the same sections being resolved multiple times
• PDP load takes >2s and most time is spent on layout section loaders
• Setting up a new Deco site and want optimal caching from the start
