Meta: > There are several papers about the pumping of a swing ³, ⁴, and ⁵ and much more. In this section, I’ll focus in particular on ⁴. Either those little numbers are references to footnotes, and so are outside of the text flow, either they are part of it. Here the text explicitely use them ("I’ll focus in particular on ⁴") but still put them in superscript with role=doc-noteref, meaning screen readers will skip them. (I simulated <sup> with unicode chars because HN doesn’t support HTML)
