Users can upload their own logo/design, see instant mockup previews on
shirts, stickers, and art prints via client-side Canvas compositing,
then save and activate the design to the store for ordering.
- Backend: POST /api/design/upload with file validation (type, size,
dimensions), Pillow processing, saves to designs/uploads/
- Frontend: /upload page with drag-and-drop, real-time mockup gallery,
activate/discard flow matching existing Design Swag pattern
- Fix: activate/delete endpoints now scan all category dirs instead of
hardcoding stickers/
- Nav: "Upload Swag" button added to header and homepage CTAs
