   DarkSpaceDepot — Launch page
   Path: MITD/v5/sites/dsd-home/assets/dsd/css/launch.css

   A conventional scrolling page. Nothing here is pinned to artwork, unlike
   home.css -- the content is longer than a screen at every width, so every
   section reflows.

   The :root block duplicates home.css deliberately. Extracting a shared layer
   means refactoring the live homepage's CSS, which is not worth doing until
   two or three section pages exist and the genuinely shared parts are obvious.
   When that happens, this block plus .site-head, .site-foot and .btn are the
   pieces that move.
