The historical HQ-1/2/3a build plans and the live-preview spec referenced sibling
Store apps (apps/store-server, apps/backoffice) as copy-sources and cited Store-only
docs. Rewrote those to describe the patterns intrinsically and to name the Store
product/repo where the scope boundary is genuine, so each plan stands alone in the
HQ repo. Technical content and task lists unchanged.
