What this guide covers
Steam lists Windows and macOS support. The official minimum requirements list Windows 10 or later, 8 GB RAM and 1 GB storage.
Source-grounded approach
The official Steam description confirms fabric selection, pattern cutting, sewing, decoration, customer commissions, reputation and coin. It does not publish a universal best build or hidden numeric formula, so this guide does not invent one.
Next step
Use the live Steam store and in-game prompts as the final authority when a detail changes.
