   Two rules in here are compliance decisions, not aesthetic ones:

   1. No figure is ever colored by sentiment. There is no green for a
      favorable number and no red for an unfavorable one, because coloring a
      figure characterizes it, and this product does not characterize
      results (spec 6.2). Every number renders in --text. If you find
      yourself adding .metric--positive, stop.

   2. The 4.41 disclaimer is styled for prominence, not tucked away. Its
      body text sits at full contrast, not --muted, and at body size. CFTC
      guidance regulates placement as well as wording (spec 6.1).
