// The visitor's color scheme for these pages: System, Light or Dark,
// remembered for the whole site. Loaded in <head> so a saved choice
// applies before the first paint. The control ships hidden and this
// reveals it, so without JavaScript a page follows the system setting
// (or the scheme it was generated with) and shows no dead control.
