Defaults to `inline=false` and downscales to `max_dimension`/`max_bytes` (4000px / 4MB by default) specifically to avoid blowing up an…

capture_window

screenshots one specific window by PID (optionally filtered by `title_contains`), not the whole display.

capture_display

screenshots one specific physical display by its index from `list_displays`, for multi-monitor setups.

list_elements

lists actionable elements for a PID (a flat, practical "what can I click" view).
