   The Spark Labs brand from sparklabs.team: signal red and ember orange on warm cream, set in a wide, heavy grotesk.
   Night sections are where the crystals glow: red under ultraviolet, green under infrared. One bold moment: the 3D
   SPARK lockup on the home page, with a real cut gem turning between the words. */
