/* ------------------------------------------------------------------------
   SOUNDROOM
   A night colour scheme: ink with a violet bias, lit by sodium-lamp amber,
   and a daytime counterpart that keeps the same violet cast rather than
   turning into cream. Two voices: Bricolage Grotesque speaks, Martian Mono
   reports numbers.

   Every colour is declared twice on purpose. The first declaration is the
   dark value, which is what a browser without light-dark() will use; the
   second adds the light half. Old browsers get the night look, which is the
   one this app was designed in, rather than an unreadable half-theme.
