/* Ski Intelligence: homepage and privacy page.

   The approved Option A concept was drawn on a fixed 1,100px canvas. This
   stylesheet rebuilds it as an ordinary responsive page: a normal 16px root,
   one container and gutter system, fluid type and spacing tokens, and a few
   layout breakpoints (30em, 48em, 52em, 60em) written in em so browser text
   settings move them too. Nothing here scales the page as a whole. */
