Inspect source boundaries, media rights notes, source-description status, and editorial-vs-factual labeling.
Routes distinguish source-supported facts from newly authored synthesis. Seasonal labels are contextual, not universal.
Evidence & rights
Source links support specific factual claims. No external image is embedded in this candidate, so media licensing remains intentionally simple.
