Eight living bears. One family, four continents.
A field atlas of range, habitat, diet, mass, and conservation — rebuilt in Astro so the data and figures can sit still long enough to be read.

What changed from the old site
The original Next.js repo covered four North American forms and a stub map. This rebuild expands to all eight living species, adds comparable mass and diet figures, conservation chips, and a quieter layout that can grow into GeoJSON range layers later.
