Advanced AI Prompt for Radix UI Popover Contextual Help System

Develop a system-wide contextual help component using Radix UI Popover. The implementation must handle [Z_INDEX_STRATEGY] to ensure the popover appears above complex layouts and other modals. Configure the Boundary and [COLLISION_PADDING] to prevent the popover from clipping at viewport edges. The [TRIGGER_TYPE] (Hover vs Click) must be optimized for both mouse and keyboard users, including appropriate delay logic for hover. Provide the accessible naming strategy using aria-labelledby to link the help content to the calling element.
