Build Your Own Bundle - two build options

Staged for review on this sandbox theme only. Neither option is live. Pick one and we finish the build.

Option A - Native Shopify fixed bundles (recommended)

What it is	Curated fixed-composition boxes, e.g. a 20-unit case tier. Customer picks a published bundle SKU, not individual units.
Backend readiness	Packing projection tested (7 unit tests), not yet wired into order-ingress or stock writes.
Risk	Low - no production database migration needed.
Time to ship	Fastest of the two - Shopify-native product/variant setup plus finishing the wiring.

Option B - Variable bundle (pick any mix of units)

What it is	Customer assembles an arbitrary mix of catch-weight units into one bundle, reservation-based allocation.
Backend readiness	12 tests pass in an isolated proof container. Production schema not migrated (still at revision 0010, needs 0011). Zero bundle units exist in production.
Risk	Higher - production migration plus new order-import/scan routes, stock-integrity risk flagged in the handover.
Time to ship	Slower - needs a storefront picker UI built from scratch plus the production migration.

Recommendation: start with Option A. Full writeup: infra/entre/reports/bundle-recommendation-2026-09-16.md
