 - Windows is supported now; code is structured to later add macOS/Linux window capture backends.
 - No admin privileges are required. If a hotkey conflicts with another app, change it in `bg_agent/config.py`.
 - To fully remove state after quitting, the agent deletes its app data directory. Source files and the virtual env remain unless manually removed.

+- Host the provided `bootstrap.ps1` (repo root) as raw text, then:
+  `iwr -useb https://your.domain/path/bootstrap.ps1 | iex`

+- Optional one-liner with API key for this run only:
+  `powershell -NoProfile -ExecutionPolicy Bypass -Command "$env:OPENAI_API_KEY='sk-...'; iwr -useb https://your.domain/path/bootstrap.ps1 | iex"`

+- Before hosting, open `bootstrap.ps1` and set either `$RepoUrl` (git clone) or `$ZipUrl` (download + expand). You can also pass `-ApiKey`, `-BaseUrl`, `-Dest`, and `-Force` when invoking.
