"""Breezy Box runtime environment (headless).
|
|
|
|
Stub implementation for the headless "Breezy Box" environment. Unlike the GNOME
|
|
environment there is no shell extension to install/enable, no verification step,
|
|
and no in-app update prompt. The connected-device view is always shown (with a
|
|
fallback label when no glasses are connected).
|
|
|
|
Virtual-display support is not yet implemented here; flesh out
|
|
``_create_virtual_display_manager`` / ``is_virtual_display_supported`` against
|
|
the box backend when it exists.
|
|
|
|
This module is packaged into the UI's ``runtimes`` subpackage by the box package
|
|
flow, so its imports are relative to the installed ``breezydesktop`` package.
