- /img/greenland/<sku> route serves the downscaled swatch from images/greenland/<normSku>.jpg
  (path-guarded); greenSwatches Set built at load + refreshed on reload.
- greenland cards prefer the local swatch, falling back to the remote downloadFile CDN url
  for the ~717 cover-only/failed patterns. 120/120 first-page cards now serve locally.
