   Palette is fixed by brief: light sky blue, neon green, white.
   White is the surface, sky blue is the structure and the interactive colour,
   neon green marks one thing only: the part of the bill you can actually change.

   The calculator is the hook, so the homepage is built around it: headline
   above, instrument below, pricing on a single line inside the instrument.
