Developing GTK Apps
Build robust GTK 4/libadwaita applications with correct architecture, lifecycle, and patterns.
Core principle: Get the foundation right before the UI. Application lifecycle, threading model, and resource management are where most GTK apps break.
Relationship to UI skill: This skill handles architecture and plumbing. For widget selection, layout, and HIG compliance, use designing-gnome-ui.
