 * served over HTTP, each a p50 the research runs hold, drawn to scale against
 * the slowest of the three. The bars grow in ten times their measured time, so
 * the eye can follow. No hosted call stands beside them: the figure here is
 * what Kai takes, on hardware of one's own.
 *
 * THE SUITE: the Decision Suite's rated tasks Kai wins, Kai's figure beside
 * Jev's on the same scale, out of 100%. A task's label is lib/kai's, drawn
 * through `t()`, so it is in the reader's language wherever lib/kai marks it
 * as authored copy (`phrase`).
