/* ============================================================================
   Portfolio - Willian Cozzi Candido
   One stylesheet for the two page types that exist: the slim one-page home and
   the case studies. Dark, flat and typography-led: one background colour, one
   accent, no decoration.
   Rules for classes that no longer exist in the markup were removed in the
   minimal-dark redesign (header nav, hero, cards, timeline, highlight numbers,
   screenshot figures, stack grid, contact card).
