RydersWorld - Lego Set Inventory

Ryder has a lot of Lego sets and no system for tracking
them, so I built one into RydersWorld. Add a set by number
and it calls the lego-api, which proxies Rebrickable and
fills in the name and catalog image automatically. The last
built date is not a field you fill in — it derives from
the task system. Link a build task to a set, mark it
complete, and the date updates itself.

The public view is a simple card grid: image, name, and how
long ago it was last built. No buttons for him to press.
Ryder is five.
