Targets
The built-in target
lattice/ice40up5k-sg48 is the only built-in target: the exact Lattice iCE40UP5K-SG48 chip/package.
It is build-ready through the open-source target flow and declares the community licence tier.
Private targets
Project-local definitions live in .forge/targets/*.json and resolve through the same Core registry.
Private definitions default to the enterprise licence tier unless they declare a lower tier explicitly.
