Manages keyboard navigation within a 2D grid following the WAI-ARIA grid pattern. Supports arrow keys for cell-to-cell navigation, Home/End for row boundaries, Ctrl+Home/Ctrl+End for grid boundaries, and Page Up/Down for custom callbacks (e.g., month navigation in calendars). Boundary navigation callbacks allow cross-grid navigation.
