+The Project category, shown while a project is selected, holds the project's name, icon, session import, actions,
 checkouts and removal. Actions belong to a project: editing them creates the project's own list
 on each selected environment, and reset returns to the environment's shared list. A project's

 Settings a repository can also declare in `t3.json`, such as the workspace for new threads,
 resolve in one order: a project override, then the environment setting, then `t3.json`, then the
 built-in default. Leave a setting on **Inherit** to let the next tier decide.
