Extract TwoStageZImagePipeline shared base from QwenZImagePipeline so all three profiles are siblings, not a chain. Add ChromaZImagePipeline on that base with diffusers ChromaImg2ImgPipeline bf16, neutral calibrated prompt, guidance 5.0, four effective steps with Diffusers truncation compensation, no Canny. Flat vendor floors from the 2026-08-29/30 oracle calibration across OpenAI (0.09), Microsoft InvisMark (0.125), Google (0.40), Meta Content Seal (0.17), seed-stability verified on Meta, full-path face-stage interaction clean through the Gemini oracle. Research record in docs/chroma1-engine-research.md with the matched-strength addendum showing Chroma1 regenerates better per unit strength but its boundaries scatter wider than qwen's. Fix text-manifest guard to reject chroma-zimage at the boundary, update all profile references from 'both' to 'all three' across src, docs, README, and python-api.
