New Runware image backend at ~$0.0006/image (FLUX.1 schnell) — 65× cheaper than Gemini 2.5 Flash Image. Provider mirrors OpenRouter's split: interface + provider + support + pricing + batch, all under the 300-line cap. Batch class uses curl_multi for true parallel A/B dispatch — wall-clock drops to the slowest single image instead of the sum. Changes: - Add PRAutoBlogger_Runware_Image_Provider + Pricing + Support + Batch - Flip PRAUTOBLOGGER_DEFAULT_IMAGE_PROVIDER/MODEL to runware:100@1 - Add prautoblogger_runware_api_key settings field (encrypted at rest) - v0.9.0 one-time migration flips legacy default model + re-derives provider - Wire runware branch into Image_Pipeline::create_default_provider() - Add runware:100@1 and runware:101@1 to Image_Model_Registry (defaults top) - Update image prompt builder: no more anthropomorphized molecules; prefer concrete human-scale scenes (gym bros, doctors, scientists) - ARCHITECTURE.md + CHANGELOG.md updated with new integration + decision - Unit tests for pricing, support, provider; update model registry test Cost impact at 100 images/day (50 articles × A/B): - Before (Gemini via OpenRouter): $3.90/day ≈ $117/mo - After (FLUX schnell via Runware): $0.06/day ≈ $1.80/mo Net saving: ~$115/mo
