/* Chronically Iconic Author. Palette from the banner (Concept D): the blue
   is the ground, emerald and silver are accents, purple comes from the quilt.
   The banner's blue lightens downward from #0d1e3c to #102545 at its bottom
   edge. The banner is always 25vw tall, so the page holds that colour to 25vw
   and keeps lightening from there, with no seam. */
