Static seeded article. Admin authoring, CMS publishing, saved preferences, and email delivery are not implemented in this frontend slice.
Start with the fields that change a buyer's risk fastest: hours, condition, location, stock number, serial visibility, and whether the seller has enough photos to support the description.
Use category-specific specs as a second pass. Excavators, loaders, telehandlers, and lift equipment need different details, so a useful marketplace should keep those fields close to the listing card and detail page.
Before contacting a seller, write down the missing details you need answered. That keeps the inquiry direct and gives the seller a clear path to respond with usable information.
