   Type:  IBM Plex Sans (UI + body), IBM Plex Mono (ticket numbers, timestamps, figures)
   Color: teal accent for the product chrome; a separate validated palette for
          status / priority pills and dashboard charts (never the same hue as
          the accent, so data never gets mistaken for UI). */
