   Palette taken verbatim from the site's own style.css (Wayback 20050205231358):
   #6666FF violet, #FF9900 orange, #FF66FF pink, #9DCEFF sky, #333333 text.
   Rebuilt as a responsive "arcade board": boxed panels with hard offset
   shadows and the original dashed accent rules (.HrBlue/.HrOrange/.HrPink)
   carried through as the site's motif. No framework, no table layout.
