Before local development, prepare the environment and install dependencies:

| 2 | mise install |
| 3 | vp install |
T3 Cloud is optional and disabled in a fresh clone. To enable it for web, desktop, and mobile source
builds, copy .env.example to .env at the repository root and set the canonical
public configuration there.
