Document the profile settings added to the launcher design and the new
Start Server detail action. The settings contract now includes a persisted
username and language choice, and the game detail overlay shows Start Server
only for installed games that can host a dedicated server.
The reference mock now includes the matching Profile controls, a server icon,
server-capable sample catalog entries, and the updated detail/settings
artboards so implementation can follow the selected design direction.
Test Plan:
- git diff --cached --check
