Build a real listing with the seller's own photos, preview it exactly as it will appear, then export a drop-in data file. Nothing is published until you commit it.
Exactly how the card renders on the site.
Your working set. Edit or remove any, including the seeded samples.
ggbb/data/_own-listings.json.ggbb/img/listings/.npm run build in ggbb/, then commit and push. The listing goes live.
Set demo to false on real listings (new ones added here are already real). Remove the seeded samples before launch.
