/* H7 Engineering — "the drawing set"
   Tokens
     film      #EEF0EE  page
     sheet     #F8F9F8  drawing panels, raised faces
     graphite  #22262B  ink, text
     steel     #5E666E  secondary text, dimension lines
     rule      #C5CBCC  hairlines
     petrol    #0E5A66  the only accent: bend lines, links, primary button, focus
     mill-scale #1E2328 / #E8ECEB  the one dark band (offer)
   Type: Archivo variable for everything (expanded widths for headings), IBM Plex Mono only inside
   drawings and the footer title block.
   Rationale: an engineering firm earns trust the way a good drawing set does — calm paper, one ink,
   precise lines, nothing decorative. Structure comes from hairline rules and an asymmetric 12-column
   grid, not cards. The one loud element is the hero drawing of a parametric part family, the firm's
   whole argument in one picture; everything around it stays quiet. */
