/* CNC Inlay Studio — a Tapawingo Labs project.

   Styled to the Tapawingo Labs brand: the night ground, the teal/amber dawn
   palette, Outfit for everything that is read and JetBrains Mono for anything
   that labels, counts, or names a machine. Section breaks are the horizon
   hairline from tapawingolabs.com rather than flat borders, so the two sites
   read as one house.

   Class names are unchanged from the original markup. */
