Labels

Render GS1-128 / UCC-128 carton shipping labels as PDF or ZPL (shared by all marketplace apps).

Platform-wide label renderer for GitHub, Vercel, AWS Marketplace, RapidAPI, and generic API clients authenticated with a platform-scoped key (or dashboard session). Also gated by SHIPPING_LABELS_ENABLED (404 when off). Optional asnContent enforces SSCC ↔ 856 MAN consistency (422 on mismatch). Does not send EDI. Shopify Admin uses the same engine via /api/shopify/embedded/labels. Letterhead/BrandProfile is never applied to label zones.
