📝 Walkthrough

Walkthrough

Font provider metadata is now stored as a typed dataclass, consumed through attributes in font-loading paths, and covered by a regression test for Matplotlib 3.11 hashing behavior.

Changes

Font provider metadata typing

Layer / File(s)	Summary
Dataclass metadata storage pyfonts/utils.py	FontProperties metadata is stored as a frozen dataclass, and the getter returns that typed object instead of a dict.
Attribute-based consumers and regression test pyfonts/main.py, tests/test_set_default.py	Default-family lookup and variant loading read provider metadata through attributes, and a regression test patches FontProperties.__hash__ before checking the Urbanist default family.
