Variant Spec Sheets

Give every product option its own specification table. Import specs from CSV, review the exact changes, and show the selected variant's details with a theme app block.

• One row per variant. Model, dimensions, material, compatibility and description are stored in app-owned Shopify metafields.
• Review before writing. The CSV preview matches variant IDs, blocks duplicates and product mismatches, and shows before/after values.
• Built for the product page. The app block updates with the selected variant and never leaves the previous option's values behind.
