/* Duration Desk — the look agreed in the v2 mockup.
 *
 * One colour rule, applied everywhere: red and blue mean the direction of the
 * duration view and nothing else. Not "good and bad", not "up and down" —
 * bearish duration is red because it maps to TBT, bullish is blue because it
 * maps to TLT. A palette that also used red for errors would make the two
 * meanings compete on the same screen, so failures are carried by an amber
 * that appears nowhere else.
