The term "spine" in literature is remarkably versatile, serving both literal and metaphorical purposes. On one level, it denotes the anatomical backbone—a physical structure described in precise, sometimes scientific, detail, as seen when authors comment on its curvature, tapering edges, or role in bodily alignment ([1], [2], [3], [4]). At the same time, the word evokes visceral sensations and emotional states: a shiver running down one’s spine can signal fear, apprehension, or even a thrill of awe ([5], [6], [7], [8]). Beyond its physicality, the spine also symbolizes inner strength, support, or vulnerability, representing the body’s core or the moral backbone of a character ([9], [10], [11]).
