/* Jamlings landing page.
   Dot-matrix, after the Nothing design language: monochrome surfaces, borderless cards on a sparse
   dot field, Doto for display type, Geist Mono for labels, and colour used only where it means
   something — the six characters, and the one action we want taken.

   Light rather than dark, because the audience is families and the illustration is a sunny room.
   The instrument stays dark, so the brightest, most colourful thing on the page is the toy itself. */
