remix-graphic-ad-from-reference

Purpose

Given one reference ad image + a target product + new copy, produce a finished static ad that keeps the reference's layout and composition but swaps the product and words for the new brand. This powers the app's "pick a Pinterest ad you like → get the same ad for your product" flow.

It does not invent layouts and it does not regenerate the whole scene from scratch. It reads the reference, then uses the engine that reproduces it faithfully:

• HTML overlay — the default. The product is cut out and placed; the background is reproduced (CSS gradient/sky/solid or a sourced photo); all copy is crisp, correctly spelled, and editable (price/discount/headline are real text, not pixels). Deterministic, $0 gen, exact brand color/font.
• GPT Image 2 (edit the reference) — only when a real photographic element is required the overlay can't fake (a hand holding the product, a model, a lifestyle/in-use scene). It runs in image-edit mode on the reference itself to preserve the composition and only swap the product + text.
