/* Palette + mark-spec choices follow the project's dataviz skill: fixed categorical order (only
   slot 1 "blue" is used here -- a single series never needs more), status colors reserved for
   pass/fail state, delta colors for trend deltas, thin marks (<=24px bars) with rounded data-ends
   anchored to a baseline. Light theme by default; dark follows prefers-color-scheme, same ramps
   re-stepped. */
