Application-level constants for Curator (build/runtime metadata).
|
|
|
|
This module derives the app version and debug flag. The version is loaded from
|
|
`pyproject.toml` (preferred) with a generated `src/_version.py` fallback for
|
|
frozen/PyInstaller builds. Debug mode is controlled via `.env` (`ENV_DEBUG`).
|
|
|
|
It is the single source of truth for app metadata used across the GUI and build
|
|
tooling (`APP_NAME`, `APP_VERSION`/`VERSION`, `APP_TITLE`, `APP_VIEWPORT`).
