/* ==========================================================================
   CAQ / BAR account dossier
   A reading document, not an instrument. Warm paper ground for a long
   morning read; the ROAS ramp is the semantic spine, so every figure in the
   document sits somewhere on the same scale from "destroyed value" to
   "cleared the bar". The 0.95x break-even line is a real decision boundary
   in this business, so the palette encodes it rather than decorating around it.
