Window Wardrobe is an independent implementation written from scratch, including all procedural pattern artwork. The idea of dressing macOS window frames was inspired by Window Sweaters (https://github.com/saragordic/window-sweaters). Only that project's README and contribution documentation were consulted. Its GPL-3.0 source, assets, charts, and pattern catalogue were not used or copied. Weather data: Open-Meteo, https://open-meteo.com/ (CC BY 4.0).
