   OSKAR South Africa — design system "The Drawing Sheet"
   The site is treated as an engineering document: white sheet, black
   line, a title block that identifies every page, drawings given equal
   weight to photographs. Chivo for text, Chivo Mono for codes and
   dimensions. OSKAR blue (sampled from the logo) for action; the pink
   revision tag from the real drawings for versions/variants only.
