The term margin in literature serves as a versatile marker that can denote both physical borders and metaphorical limits. It is frequently used to describe literal boundaries, such as the edge of a brook ([1]), the periphery of a thicket ([2]), or even the bank of a pond ([3]), thereby enriching the depiction of landscapes and settings. At the same time, margin appears as a space for annotation and correction on a page—as seen when page and line numbers are noted ([4]) or when scribbled comments and corrections are made in the margin ([5], [6]). Moreover, it functions metaphorically to signal the edge of time or possibility, as when a narrow margin of delay is all that separates success from failure ([7], [8]) or when it suggests the room available for unforeseen variations ([9]). Thus, literature uses margin to highlight that delicate border between the central focus and its outer limits, both in material form and in abstract concepts.
