Spec Table reads product or variant metafields and shows storefront specs tables through one Theme App Extension block. Merchants set labels, namespace keys, priority rules on product traits or taxonomy plus optional metafield match conditions, and PDP preferences. Semi-automatic onboarding builds starter rows by merging metafields from selected catalog products across product and variant levels, then refining in the editor. Configuration stays on Shopify app installations.

• Build starter template rows by merging metafields from products you select.
• Rules assign templates using traits, tags, taxonomy, metafield match conditions.
• Theme App Extension renders PDP tables and hides blank rows automatically.
• Titles, booleans, URLs, and storefront styling configurable globally.
• Embedded Polaris admin for templates, product binding, and settings.
