Variant-safe Liquid section | independent demo

ThemeCare created a variant-safe product section with Liquid, JavaScript and CSS, a source ZIP, installation guidance, an acceptance checklist and rollback notes. OpenAI/Codex performed technical production and verification; the named individual remains accountable.

The bounded component uses actual variant IDs from Liquid, native product-form submission, supported-variant checks and synchronized price/image state. Its scope is at most 100 variants, one unit per addition and one-time purchases. Subscriptions, B2B, quantity restrictions, cart-drawer rebuilds and complex app integrations are outside this asset.

On 2026-10-02, official Shopify CLI Theme Check was run on the exact three source files in a minimal standalone theme fixture. The recommended configuration enabled 83 checks; diagnostics were empty and the exit code was 0. This is dated static evidence, not a claim of current merchant rendering, checkout correctness or app compatibility.

No real merchant store, customer data or payment was used. This is independent demonstration work, not client experience. A merchant installation still requires the documented real-theme acceptance checks before publication.
