Lorem Ipsum is placeholder text used since the 1500s in the printing and typesetting industry. It's derived from a work by Cicero (45 BC) called "de Finibus Bonorum et Malorum" (On the Ends of Good and Evil).

Designers and developers use it to fill layout mockups with realistic-looking text, test typography and font rendering, prototype page layouts and spacing, and demonstrate visual design without distracting content. The text looks like readable English but has no actual meaning, letting viewers focus on design rather than content.
