Opening a repository shows its model card, rendered from markdown, with its base model, license and languages above it; the listing names each repository's base model and license under its name. The card is a stranger's text: raw HTML and dangerous links are dropped, images are shown as links rather than loaded, and relative links point into the repository. Adds github.com/yuin/goldmark for the markdown. Co-Authored-By: Claude Opus 5.5 (1M context) <noreply@anthropic.com>
