/* Working Papers, drawn.
   Evidence is rebuilt as original figures from verified account data; interpretation sits beside it.
   Type: one family (Archivo). Normal width is Johnny's voice and the figures' values; condensed width is
   labels, axes and source lines.
   Color: a cool light ground. Figures use three tones with one meaning each:
     ink   = the documented current value
     grey  = the comparison or context value
     teal  = the signal: the change, the client's position, or the gap worth pointing at.
   Teal never means "good"; direction is carried by position and sign. Palette validated for CVD separation
   (teal vs grey ΔE ≥ 16, teal vs ink ΔE ≥ 36); every value is direct-labeled, which covers grey's contrast. */
