/* =========================================================================
   GOOG_ — design system
   -------------------------------------------------------------------------
   Everything here is derived from assets/pfp.png: flat vector, heavy navy
   outline, Google's four colours on white paper. So the page is built like
   printed matter — 3px hard borders, offset shadows with zero blur, colour
   used to mean something rather than to decorate.

   Contrast note: Google's brand blue (#4285F4), yellow (#FBBC05) and green
   (#34A853) all fail 4.5:1 on white. Each appears here ONLY as a fill behind
   navy text, or as a border. Body text uses the darker accessible variants
   (#1A73E8 / #C5221F / #188038). Yellow is never used as text on paper.
