Reuse without losing the research context

Stable figure URLs

Each figure has a permanent landing page plus direct SVG and PNG asset URLs so citations and embeds do not depend on a screenshot filename.

Canonical study provenance

The figure page keeps the data date, source study, third-party evidence label, and preferred citation together.

Editorial citation

Publishers can cite the canonical study naturally in their own coverage. Reuse does not require a followed backlink.

Safe static embeds

Generated image embeds use a nofollow attribution link by default and keep visible Grizzly Bulls branding inside the asset.
