2) Ownership map

Assign planning, production, QA, and measurement owners. Publish the map where the team already works.

• speed budget for theme scripts (delivery gate)
• collection cannibalization review (review gate)

4) Delivery rhythm

Ship in small increments. After each release, add links to the Shopify hub and sibling cluster pages.

5) Learning loop
