Tag product images with their colour during sync (both Printful and Printify providers). Printify images are cherry-picked: hero colour keeps all angles, other colours keep front + back only. Printful MockupEnricher now generates mockups per colour from the color_variant_map. PDP gallery filters by the selected colour, falling back to all images when the selected colour has none. Fix option name mismatch (Printify "Colors" vs variant "Color") by singularizing in Product.option_types. Generator creates multi-colour apparel products so mock data matches real sync behaviour.

Oban worker that enriches Printful products with extra mockup angle images.
|
|
|
|
After product sync, Printful products only have front-view preview images.
|
|
This worker uses the legacy mockup generator API to produce extra angles
|
|
(back, left, right, etc.) and appends them as additional product images.
|
|
|
|
The hero colour gets full angle coverage (front, back, left, right).
|
|
Other colours get a front-view mockup only (one API call each).
|
|
|
|
Each product is processed as a separate job so failures don't block others.
|
|
The temporary S3 URLs from the mockup generator are downloaded via the
|
|
existing ImageDownloadWorker pipeline.
