It could be a Portland reference. The city had a gourmet chocolate shop called Cacao that served "drinking chocolate" from 2005 until 2020. I know because I went in there after getting lost and drenched in a Portland February, and the staff there were kind enough to bring me towels and let me wait out the downpour while I sipped chocolate.
But more than likely it's just a reference to Apple's Cocoa api.
Am I missing something, is the name/reference just "cacao"?
Many languages spell cocoa that way, so I would take the name as cocoa-but-exotic or cocoa-but-foreign.
