/* ===========================================================================
   CloudShift — launch site
   ---------------------------------------------------------------------------
   The palette is built from the two colours sampled out of the logo: the blue
   of the C-arc (#1d7cfd) and the orange of the arrow and "SHIFT" (#ff8602).
   Everything else is a *tint* of that blue rather than a neutral grey — the
   page background, the panel fills, the borders and the type all sit on hue
   ~215, so the whole site reads as one colour family with the logo instead of
   as white-with-a-blue-button.

   Deliberately light. Deep shades are reserved for type and for the app
   screenshots, which are dark and are meant to stand out as "the product".

   Interactive blue is --brand-deep, not --brand: the lighter logo blue doesn't
   clear contrast ratios against a pale background, so the bright tone is used
   for fills and washes and the deeper one for anything you have to read.
