6"""Legacy Qt registries for fonts and size policies.

8These classes materialise ``FontSpec`` / ``SizePolicySpec`` domain objects 

9into live Qt objects and expose them as class-level attributes for use by 

10widget code. They are populated by calling ``initFonts()`` / 

11``initSizePolicy()`` once during application startup.
