Board-specific repositories must appear before generic repositories (i.e., gems) in 'REPOSITORIES' to select board-specific sculpt/ configuration snippets over the defaults provided by gems. When listing the board-specific repositories last, Sculpt images for the PinePhone or MNT Reform may wrongly include launchers and presets of the PC version.
