Some checks failed
CI / Windows build (push) Has been cancelled
Two tests asserted pre-refactor behavior: - pen_config_test expected the old pressureGamma default of 1.0; it is now the natural curve (the pen-feel feature). Also assert the new eraser defaults. - widget_test pumped HomeScreen without localization delegates, which the now-localized app bar requires. Provide the delegates. Full suite: 258/258 pass.
