Tell it the way an editor would cut a paper-collage explainer. Torn paper in mustard, navy, red and sage. Duotone cut-outs in an archive style, generated as images and then cut and toned in code. A caption strip that lands word by word with the voice. The story moves from the 1688 Basel dissertation that first named nostalgia as a disease, through the scholarship that reframed it as longing, to research that treats it as an act of imagination.
