## Description

<!-- SECTION:DESCRIPTION:BEGIN -->
Brought the rspace.online/rswag module to feature parity with the standalone rswag.online (Next.js + FastAPI + PostgreSQL) application. rSwag now owns design tools, product catalog, mockups, POD clients, dithering, and AI generation. rCart owns cart/checkout/payments/order lifecycle. A bridge connects them via catalog ingest and fulfillment routing.

## What was built

### Phase 1: POD Provider Clients
- `modules/rswag/pod/types.ts` — shared POD TypeScript interfaces
- `modules/rswag/pod/printful.ts` — Printful v2 API client (catalog variants, mockup generation, order creation, sandbox mode)
- `modules/rswag/pod/prodigi.ts` — Prodigi v4 API client (orders, quotes, status)

### Phase 2: Enhanced Image Processing
- `modules/rswag/dither.ts` — 11 dithering algorithms (8 error diffusion + 3 ordered), median-cut quantization, screen-print color separations
- `modules/rswag/mockup.ts` — Sharp-based mockup compositor with SVG templates + Printful API fallback

### Phase 3: AI Design Generation
- Gemini-powered design generation (gemini-2.5-flash-image)
- User artwork upload (PNG/JPEG/WebP, min 500x500, max 10MB)
- Design lifecycle: draft → active → paused → removed

### Phase 4: Product Catalog & Mockup Routes
- ~15 new API routes for designs, mockups, dithering, storefront, fulfillment
- Filesystem-based design storage with in-memory index
- 24hr cache for images, LRU caches for dithered/mockup results

### Phase 5: Fulfillment Bridge
- `modules/rswag/fulfillment.ts` — order routing to Printful/Prodigi
- Webhook parsers for shipment tracking updates
- Tracking info lookup

### Phase 6: Frontend Design Tools UI
- 4-tab layout in folk-swag-designer (Browse, Create, HitherDither, Orders)
- Browse: product grid with search/filter/add-to-cart
- Create: AI Generate, Upload, My Designs sub-modes
- HitherDither: algorithm picker, color count, live preview, screen-print separations
- Orders: fulfillment status and tracking

### Phase 7: Revenue Sankey & Enhanced Landing
- `folk-revenue-sankey` web component with animated SVG flow + draggable sliders
- Updated landing page with Sankey embed and new feature descriptions

### Phase 8: Admin & Polish
- Admin routes: design sync, product override, analytics summary
- Schema migration v1→v2 for existing designs
- Extended products.ts with POD SKUs and StorefrontProduct type

- [x] #4 ~15 new API routes for designs, mockups, dithering, storefront, fulfillment
- [x] #5 Fulfillment bridge routes orders to correct POD provider
- [x] #6 4-tab frontend UI (Browse, Create, HitherDither, Orders)
- [x] #7 Interactive revenue Sankey on landing page
- [x] #8 TypeScript compiles cleanly (zero errors)
<!-- AC:END -->

## Final Summary

<!-- SECTION:FINAL_SUMMARY:BEGIN -->
All 8 phases implemented in a single session. Created 7 new files (pod/types.ts, pod/printful.ts, pod/prodigi.ts, dither.ts, mockup.ts, fulfillment.ts, folk-revenue-sankey.ts) and modified 6 existing files (schemas.ts, products.ts, mod.ts, folk-swag-designer.ts, landing.ts, swag.css). TypeScript compiles with zero errors. Ported Python reference code (printful_client.py, prodigi_client.py, dither_service.py, design_generator.py) to TypeScript.
