OpenArt.ai stamps free-plan generations with a semi-transparent white "OpenArt" wordmark (bowtie/infinity icon + brand name) placed near the CENTER of the frame rather than in a corner. Confirmed from a customer- reported raiw-app production case where the mark went completely undetected and unremoved, with no C2PA/EXIF/TC260 signal for identify to fall back on. - Add a new "cc" (frame-center) corner mode to the shared TextMarkConfig/TextMarkEngine base, alongside the existing corner/edge anchors. - Add openart_engine.py, following the existing text-mark engine pattern. No real capture exists (OpenArt requires an account, out of scope to create), so the bundled alpha asset is a procedural reconstruction of the public logo and the NCC threshold is an explicitly-labeled provisional guess, not a measured calibration. - Register the mark in watermark_registry.py, which auto-derives identify's platform attribution. - Add tests/test_openart_engine.py (synthetic composites only) plus registry/identify test coverage, and document the mark and its calibration caveats in README.md, docs/supported-signals.md, docs/module-internals.md, and the skill's commands.md.
