   Design intent: dark, quiet, monochrome chrome — per-trip colors (set as
   --trip-color by PHP) are the only saturated thing on the page, so the
   data stays the loudest element. The 8 trip colors are validated for CVD
   separation and ≥3:1 contrast against --surface; identity never rides on
   color alone (every colored mark is labeled or tooltipped).
