/*
  turingos-home.css — the Turing AI OS home page (turingos.html).

  Loaded after turingos.css, which the other OS pages (download, install,
  credits, thanks…) still share: that file keeps the navbar, the scroll reveal
  and the voice picker; this one is the home page's own layout, prefixed th-
  so neither can restyle the other.

  The dark sections take their colour from the wallpaper in the screenshots —
  the aurora night the desk ships with — so the pictures sit in the page
  rather than on it.
