tests/marketplace/ai-colorways.test.js — 6 cases by default (validation,
mock shape, cost-tracker wrapper sanity, DB column existence) and a 7th
opt-in REAL Gemini round-trip when WALLCO_TEST_REAL=1. Verifies:
  - PNG written to public/marketplace/uploads/
  - row persisted with ai_generated=true
  - cost-tracker logGemini called (smoke-loadable)
