One bridge for every field

A compact, dependency-free runtime binds the whole field set to the correct product form.

Values travel from the product page to Shopify. Nothing is sent back to Cart Field Studio.

Compatibility with evidence

Verified adapters.
A universal fallback.

Horizon and Dawn are tested against maintained fixtures. Other Online Store 2.0 themes use standards-based form discovery and a compatibility report—never a vague “works everywhere” promise.
