/* Stepdrum — the machine laid out flat.
   Under the name, across the whole page, is the app's own near-black stage, and on it a working
   drawing of the machine: the stepped drum unrolled into a sheet that travels past the eight
   setting columns, the number wheels above. Around it, the site's own sheet: drafting paper, ink,
   Young Serif, and ruby. The stage and the app's screenshots look the same in the light and the
   dark scheme: they are objects, not surfaces. */
