theme-parity
INTERNAL DEV WORKFLOW for WpfHexEditor — Claude self-invokes after editing Themes/<Theme>/Colors.xaml or *Theme.xaml to verify the 18 themes share the same key surface. Detects: theme-key-missing (key in Dark but not in the edited theme), theme-key-orphan (key only in this theme), theme-color-no-brush (Color without paired SolidColorBrush), theme-merge-order (wrapper merges Colors.xaml after Menu.xaml/TabControl.xaml). Skip on: edits outside the Themes/ tree.
