Sizes are normalized into a shared format (region labels stripped, formats standardized) before comparison, ensuring consistent matching across sources.

• ·Collectibles have no size, solved by matching by product identity.
• ·US 8.5 and EU 42 are distinct types in provider data, the correct type is resolved before comparison.
• ·Normalization runs on both sides of the comparison, to ensure both sides are normalized.

Each mapping is persisted with a status (mapped, not_found, manual_review). Failed items are skipped on subsequent runs, avoiding redundant API calls, the dashboard give the user the ability to resolve manually the unresolved cases forre-matching.

• ·A product deleted from provider transitions to status not_found and excluded from future runs.
• ·Re-mapping can be triggered manually from the dashboard after fixing the Shopify product metadata.

Caddy handles HTTPS via Cloudflare origin certificates, while PM2 runs and monitors all services. A Docker setup is available as a fallback for portability.

• ·Log rotation prevents disk exhaustion on the host.
• ·All traffic is proxied through Cloudflare, blocking direct origin access.
