|--------|------------|
| `path = "../lib"` | Local directory (validated, added to search paths) |
| `git = "url"` | Cloned to `.pascal/deps/<name>` |
| `"1.0"` (version) | Registry cache `.pascal/registry/<name>-<version>/` |

Set `PASCAL_REGISTRY` for registry URL. Vendor packages locally when offline.

## Semver

Version constraints use major.minor.patch comparison via `deps::version_satisfies`.
