Backend:
- product_image_service.py: Replaced direct wavespeed_client.generate_image()
with generate_image() from main_image_generation (unified entry point)
- This ensures subscription pre-flight validation (_validate_image_operation)
and usage tracking (_track_image_operation_usage) are enforced
- Removed _generate_image_with_retry method and WaveSpeedClient dependency
- Animation/video/avatar services already route through ImageStudioManager - no changes needed
Frontend:
- useProductMarketing.ts: Added formatError() helper for 402/429 detection
across all 8 API operations
- useCampaignCreator.ts: Added formatError() helper for 402/429 detection
across all 13 API operations
- All error messages now surface subscription limits with upgrade prompts
