Original-author provenance: All artwork, diagram coordinates, task definitions, prompts and bilingual teaching copy in this package were authored from original unbranded geometric code for this project. PNGs are deterministic rasterizations of the supplied SVGs. Every uploaded PNG remains role=input; SVGs and observation guides are design/review material, not model outputs. No third-party photograph, image, prompt, trademark, external font or generated media was copied. The author permits these original materials for this project and its practice downloads. This is an author source/rights/language check, not independent capability/entity/editorial review, legal exclusivity, model validation or publication approval. No model/provider or paid call was made.
