Publish updated lead times to central data store

Stale lead time sheets cause wrong delivery estimates and support tickets. Keep central lead-time data current so customers and fulfillment see accurate times.

Overview

When lead-time spreadsheets go stale, storefront estimates and fulfillment priorities break, increasing support load and order friction. Centralizing sheet rows into a single lead-time resource makes delivery estimates consistent so customers and fulfillment teams see accurate times within minutes.
