/* SQLDesk site — the shared foundation.

   The palette is the product's own tokens.less: the site and the app are one
   design system, deliberately.

   Two things here differ from the pages that predate this file, and both are
   on purpose:

   - `--canvas` is #f6f8f9, which is what the application actually paints on
     `body`. The token layer says @n-50 (#fbfaf9, warm) and `base.less` paints
     #f6f8f9 (cool) over the top of it, so the site matching the token did not
     match the product. It matches the product now. Worth reconciling in the
     app one day; the site should not be the thing that moves.
   - There is no `prefers-color-scheme: dark` block. SQLDesk itself is light
     everywhere except the wall display, so a site that went dark on half its
     readers was the odd one out.
