   Sampled off the approved brand art: assets/avatar.png corner pixel is rgb(255,80,0).
   orange  #ff5000  the brand field. Hero, the refusal band, every accent rule.
   ink     #0f0d0b  near black. Body type on paper, background on the dark bands.
   paper   #f7f3ee  warm off white. The long reading sections sit here, not on orange.
   red/green are muted book colours, not neon, so the figure reads before the colour does.
   Type:  Oswald 500/600/700 condensed for headlines (blunt, signage register)
          Inter 400/500/600 for body (long paragraphs, high legibility)
          IBM Plex Mono 400/500/600 for every number, formula and the CA
   Spacing scale: 6 / 10 / 14 / 20 / 28 / 40 / 56 / 80 / 112 px
   Radius: 4px structural, 999px pills only. Corners stay tight on purpose.
   Motion idiom: one 120ms ease-out translate on interactive chrome. Nothing else moves.
