The slot-based CMS underneath FATCOMMA. Every object and record has a clear shape and a clear place, so content is organised the way a developer expects.
FATCOMMA needed content, channels, streams and users modelled properly rather than bolted onto a generic CMS. Slot CMS is that model: typed slots, predictable records, and an admin that reflects the shape of the data instead of hiding it.
Structure first. A CMS that was designed, not one that grew.
