/**

* Browser globals for specs that pull browser-bound modules. Import this
|
|
* FIRST in a spec file: unlike statements after imports (which vitest
|
|
* hoists above the module body), an import statement evaluates in order,
|
|
* so this runs before any later import's module graph (xterm's UMD wrapper
|
|
* checks `self` and its color defaults probe `document` at evaluation time;
|
|
* window/localStorage are only touched at runtime by the store).
