/* jam/public/ui/landing.css — the front door. reality.twoplanets.org's front page, said as the
   jam: one centred column, a living glyph over a spaced mono wordmark, hairline bands, a grid of
   tiles with a door in it, a question and a note. The studio's ground and greys; IBM Plex Mono
   for the headings and every label, Atkinson for what someone said. The screen in the middle is
   the jam's real wall (ui/wall.css) on a simulated jam. */
