/* The Last Board Game · Open Sky: internal website draft. Palette, type and voice: brand-ideas/opensky/README.md.
   The sky is one long gradient, sampled from the key picture, that the page scrolls down through:
   night at the top of the hero, peach where the sky ends and the table begins. Below the sky the page
   is plain sections; the flat tiles in their diagrams are drawn at the end of this file. */
