/*
  OneDesktop marketing site.

  Palette taken from the design direction's PAGES, not from its token file. That matters:
  assets/styles.css ships a light set (#f2f2f3 ground, #1d1f20 ink), but every page
  overrides it inline with a dark one, and the README says so -- "all layout and colour are
  inline styles on the elements". Reading the tokens and not the markup produces a light
  site that looks nothing like the screenshots.

  The real set, lifted from index.html's own wrapper:

      --color-bg      #010f23
      --color-text    #e8eef7
      --color-accent  #3d8fd1
      --color-divider rgba(255,255,255,.12)

  Which is the application's palette exactly -- #010f23 is the sign-in page's ground. The
  site and the product are the same surface, and arriving at one from the other should feel
  like walking through a door rather than between two companies.
