Arrow cursors serve as the baseline indicator of mouse position, signaling to users that the area underneath isn't interactive. Think of it as a "neutral gear" for the mouse—when users aren't hovering over clickable links, selectable text, or other interactive elements, the arrow cursor is the go-to default.

This unassuming cursor shape is your users' home base, setting the stage for all other cursor styles that provide specific context or actions. Employing the arrow cursor as the default helps maintain a clean, user-friendly environment, reducing visual noise and streamlining user interactions.
